### Hypothesis Testing for Mean Monthly RentOn their website, a property management company states that the mean monthly rent for apartments on the east side of town is $675. A researcher for a consumer advocacy group believes that, due to the construction of newer apartment complexes in neighboring towns, the mean monthly rent on the east side, μ, is now lower. A random sample of 15 monthly rents for apartments on the east side has a mean of $673, with a standard deviation of $19.Assume that current monthly rents for apartments on the east side are approximately normally distributed. Based on the sample, is there enough evidence to conclude, at the 0.05 level of significance, that the population mean monthly rent is now less than what is stated on the website?Perform a [one-tailed test](#). Then complete the parts below.Carry your intermediate computations to three or more decimal places. (If necessary, consult a [list of formulas](#).)---#### (a) State the Null Hypothesis $ H_0 $ and the Alternative Hypothesis $ H_1 $:$ H_0 : $ [Enter Answer Here] $ H_1 : $ [Enter Answer Here]#### (b) Determine the Type of [Test Statistic](#) to Use:[Choose one from the dropdown menu]#### (c) Find the Value of the Test Statistic:(Round to three or more decimal places.)[Enter Answer Here]#### (d) Find the *p*-value:(Round to three or more decimal places.)[Enter Answer Here]#### (e) Conclusion:Can we conclude that the mean monthly rent for apartments on the east side is less than what is stated on the website?- [Yes]- [No]---### Diagram ExplanationTo the right of the question is a reference diagram with symbols commonly used in statistics, such as:- μ (mu) representing population mean- σ (sigma) representing population standard deviation- x̄ (x-bar) representing sample mean- s representing sample standard deviation- Various forms of hypothesis notation (e.g., ≤, ≥, <, >)This diagram may assist in setting up the hypotheses and understanding computations.

The number of peas in a pod varies from farm to farm. In a random sample of 50 pods from farm A, there was a mean of 4.2 peas per pod with a standard deviation of 1.03 peas per pod. In a random sample of 50 pods from farm B, there was a mean of 5.1 peas per pod with a standard deviation of 1.92 peas per pod. Agricultural researchers want to find evidence whether the pods from farm B have more peas per pod on average. What is the appropriate hypothesis test? a paired t-test for a mean difference a one-sample z-test for a population mean a two-sample t-test for a difference in means a one-sample z-test for a population proportion a two-sample z-test for a difference in proportions
The census bureau reported that the mean household income in Hayward in 2019 was $86,744 with a standard deviation of $18,700. A simple random sample of 150 households from Hayward had a mean income of $89,396 with a standard deviation of $23,156. Find the probability that a sample of this size will indicate a mean of $89,396 or more?
A parenting magazine reports that the average amount of wireless data used by teenagers each month is 10 Gb. For her science fair project, Ella sets out to prove the magazine wrong. She claims that the mean among teenagers in her area is less than reported. Ella collects information from a simple random sample of 4 teenagers at her high school, and calculates a mean of 8.4 Gb per month with a standard deviation of 2.2 Gb per month. Assume that the population distribution is approximately normal. Test Ella's claim at the 0.05 level of significance. Step 1 of 3: State the null and alternative hypotheses for the test. Fill in the blank below. Η :μ H₂H = 10 10
For a study conducted by the research department of a pharmaceutical company, 245 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 225 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 $3.60. 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 H₁ H₂ between the mean spending on prescription allergy relief medication (₁) and the mean spending on non-prescription…
A report about how American college students manage their finances includes data from a survey of college students. Each person in a representative sample of 793 college students was asked if they had one or more credit cards and if so, whether they paid their balance in full each month. There were 500 who paid in full each month. For this sample of 500 students, the sample mean credit card balance was reported to be $825. The sample standard deviation of the credit card balances for these 500 students was not reported, but for purposes of this exercise, suppose that it was $195. Is there convincing evidence that college students who pay their credit card balance in full each month have a mean balance that is lower than $907, the value reported for all college students with credit cards? Carry out a hypothesis test using a significance level of 0.01. In USE SALT State the appropriate null and alternative hypotheses. Но: и 907 Но: и 3D 907 На: и # 907 a' O Ho: µ = 907 H: H 907 Н: и…

Imagine that every elementary school in California is measured on several characteristics and then given an overall Quality Score. In Los Angeles Unified School District, the schools have an average (mean) quality score of 101.8 with a standard deviation of 7.2. One school in Los Angeles, Carver Elementary, gets a quality score of 104.5. In San Francisco Unified School District, the schools have an average (mean) quality score of 102.3 with a standard deviation of 9.4. One school in San Francisco, Bryant Elementary, gets a quality score of 99.5. Find the Z-scores for both of these two schools (Carver Elementary in Los Angeles, and Bryant Elementary in San Francisco)
A college administrator wants to see if students in different majors tend to have differing amounts of study time. The administrator collects the following data from 15 students in Sociology, 10 students in Engineering, and 12 students in History. The Sociology majors report an average of 10 hours studies per week and a standard deviation of 3 hours. The Engineering students report an average of 15 hours per week with a standard deviation of 7 hours. The History majors report an average of 12 hours studied and a standard deviation of 4 hours. The data can be summarized as follows: Major n Mean Study Hours Standard deviation Sociology 15 10 hours 3 hours Engineering 10 15 hours 7 hours History 12 12 hours 4 hours Does this data provide evidence for the notion that students in different majors study different amounts? Use α = .05
The shape of the distribution of the time required to get an oil change at a 20-minuteoil-change facility is unknown. However, records indicate that the mean time is 21.2 minutes, and the standard deviation is 4.5 minutes. Complete parts (a) through (c).
Suppose that the quarterly sales levels among healthcare information systems companies are approximately normally distributed with a mean of 12 million dollars and a standard deviation of 1.1 million dollars. One health care information systems company considers a quarter a "failure" if its sales level that quarter is in the bottom 15% of all quarterly sales levels. Determine the sales level (in millions of dollars) that is the cutoff between quarters that are considered "failures" by that company and quarters that are not. Carry your intermediate computations to at least four decimal places. Round your answer to one decimal place.
