The historical reports from two major networks showed that the mean number of commercials aired during prime time was equal for both networks last year. In order to find out whether they still air the same number of commercials on average or not, random and independent samples of 100 recent prime time airings from both networks have been considered. The first network aired a mean of 109.5 commercials during prime time with a standard deviation of 5.2. The second network aired a mean of 110.5 commercials during prime time with a standard deviation of 5.3. Since the sample sizes are quite large, assume that the population standard deviations can be estimated to be equal to the sample standard deviations, 5.2 and 5.3. At the 0.10 level of significance, is there sufficient evidence to support the claim that the mean number, $\mu_1$, of commercials aired during prime time by the first station is not equal to the mean number, $\mu_2$, of commercials aired during prime time by the second station? Perform a two-tailed test. Then complete the parts below.Carry your intermediate computations to at least three decimal places. (If necessary, consult a list of formulas.) (a) State the null hypothesis $H_0$ and the alternative hypothesis $H_1$.$ H_0 $: [ ]$ H_1 $: [ ](b) Determine the type of test statistic to use.(Choose one) [ ](c) Find the value of the test statistic. (Round to three or more decimal places.)[ ](d) Find the two critical values at the 0.10 level of significance. (Round to three or more decimal places.)[ ] and [ ]---### Diagram ExplanationThe diagram consists of boxes for inputting:- Null Hypothesis ($ H_0 $)- Alternative Hypothesis ($ H_1 $)- Test statistic type (selection box)- Test statistic value- Two critical valuesMathematical symbols and symbols for mean ($\bar{x}$), proportion ($\hat{p}$), and standard deviation ($\sigma$, $s$) are shown, alongside plus/minus symbols for calculations.An "Explanation" button is present for additional help, as well as a "Check" button to validate inputs. ### Steps for Conducting a Hypothesis Test**Objective:**Determine if the mean number of commercials aired during prime time by the first station is not equal to the mean number of commercials aired during prime time by the second station using a two-tailed test.#### Steps to Follow:1. **State Hypotheses:** - **Null Hypothesis $ H_0 $:** $ H_0 $ represents the claim that there is no difference in the mean number of commercials aired between the two stations. - **Alternative Hypothesis $ H_1 $:** $ H_1 $ indicates that the means are different.2. **Determine the Test Statistic:** - Choose the type of test statistic appropriate for the hypothesis being tested (not specified in the image, but typically a t-test or z-test).3. **Calculate the Test Statistic:** - Perform calculations to find the test statistic. It's essential to round this value to three or more decimal places for precision.4. **Find Critical Values:** - Determine the critical values at the 0.10 level of significance. These values set the threshold for deciding whether to reject $ H_0 $.5. **Decision Making:** - Based on the critical values and test statistic, decide whether the data supports the claim that there is a significant difference between the two means. - A simple choice between "Yes" or "No" can be made to conclude the test.#### Additional Notes:- Ensure all intermediate computations carry at least three decimal places.- Several statistical symbols and their functions are present on-screen to facilitate the calculations (e.g., means, standard deviations).This test helps determine whether observable differences in commercial airtime are statistically significant, thus guiding broadcasting decisions.

A new small business wants to know if its current radio advertising is effective. The owners decide to look at the mean number of customers who make a purchase in the store on days immediately following days when the radio ads are played as compared to the mean for those days following days when no radio advertisements are played. They found that for 13 days following no advertisements, the mean was 23.8 purchasing customers with a standard deviation of 1.4 customers. On 8 days following advertising, the mean was 24.4 purchasing customers with a standard deviation of 2.2 customers. Test the claim, at the 0.10 level, that the mean number of customers who make a purchase in the store is lower for days following no advertising compared to days following advertising. Assume that both populations are approximately normal and that the population variances are equal. Let days following no advertisements be Population 1 and let days following advertising be Population 2. Step 2 of 3: Compute…
The Iowa Department of Transportation repaired hundreds of bridges in 1993. To check the average cost to repair a bridge, a random sample of n-55 bridges was chosen.

For a study conducted by the research department of a pharmaceutical company, 235 randomly selected individuals were asked to report the amount of money they spend annually on prescription allergy relief medication. The sample mean was found to be $17.80 with a standard deviation of $4.30 . A random sample of 250 individuals was selected independently of the first sample. These individuals reported their annual spending on non-prescription allergy relief medication. The mean of the second sample was found to be $18.20 with a standard deviation of $4.00 . As the sample sizes were quite large, it was assumed that the respective population standard deviations of the spending for prescription and non-prescription allergy relief medication could be estimated as the respective sample standard deviation values given above. Construct a 90% confidence interval for the difference −μ1μ2 between the mean spending on prescription allergy relief medication ( μ1 ) and the mean…
A certain prescription medicine is supposed to contain an average of 250 parts per million (ppm) of a certain chemical. If the concentration is higher than this, the drug may cause harmful side effects; if it is lower, the drug may be ineffective. The manufacturer runs a check to see if the mean concentration in a large shipment conforms to the target level of 250 ppm or not. A simple random sample of 100 portions is tested, and the sample mean concentration is found to be 247 ppm. The sample concentration standard deviation is s = 12 ppm. Suppose that the p-value was 0.0259. What is the appropriate conclusion to make if α = 0.05? Group of answer choices Fail to reject H0. We have insufficient evidence to conclude that the mean concentration is different from 250 ppm. Fail to reject H0. We have sufficient evidence to conclude that the mean concentration is less than 250 ppm. Reject H0. We have insufficient evidence to conclude that the mean concentration is less than 250…

An important measure in the study of contagious infectious diseases is the number of cases directly generated by one previous case. Jessica is an epidemiologist studying the spread of an infectious disease in her country. She claimed that the mean number of cases directly generated by one previous case is now greater than 1.2. A study of 12 randomly selected cases of the disease is conducted and finds the sample mean number of cases directly generated by one previous case to be 1.5 with a sample standard deviation of 0.7. Assume that the population of the number of cases directly generated by one previous case is approximately normally distributed. Complete the parts below to perform a hypothesis test to see if there is enough evidence, at the 0.10 level of significance, to support the claim that u, the mean number of cases directly generated by one previous case, is greater than 1.2. (a) State the null hypothesis H, and the alternative hypothesis H, that you would use for the test.…
Fran is training for her first marathon, and she wants to know if there is a significant difference between the mean number of miles run each week by group runners and individual runners who are training for marathons. She interviews 37 randomly selected people who train in groups, and finds that they run a mean of 47.7 miles per week. Assume that the population standard deviation for group runners is known to be 3.3 miles per week. She also interviews a random sample of 49 people who train on their own and finds that they run a mean of 49.4 miles per week. Assume that the population standard deviation for people who run by themselves is 4.4 miles per week. Test the claim at the 0.10 level of significance. Let group runners training for marathons be Population 1 and let individual runners training for marathons be Population 2. Step 2 of 3 : Compute the value of the test statistic. Round your answer to two decimal places.
The National Coalition on Healthcare suggests that the mean annual premium that a health insurer charges an employer for a health plan covering a family of four averaged $13,000 in 2009. A sample of 30 families of four yields a mean annual premium paid by their employer to be $13,500 with a sample standard deviation of $300. We are interested in whether the mean annual premium that a health insurer charges an employer for a health plan covering a family of four is different from $13,000 using a significance level of 0.10. Select one: a. tdata = 9.129, do not reject Ho. b. tdata = 9.129, reject Ho. c. tdata = -9.129, do not reject Ho. O d. tdata = 4.156, reject Ho.
