A production filling operation has a historical standard deviation of 4 ounces. When in proper adjustment, the mean filling weight for the production process is 30 ounces. A quality control inspector periodically selects at random 64 containers and uses the sample mean filling weight of 28.6 ounces to see if the process is in proper adjustment or not. Using a standardized test statistic to test the hypothesis at the 5% level of significance, one can reject the null hypothesis and infer that the process is out of proper adjustment. O True O False

A metropolitan transportation authority has set a bus mechanical reliability goal of 3,800 bus miles. Bus mechanical reliability is measured specifically as the number of bus miles between mechanical road calls. Suppose a sample of 100 buses resulted in a sample mean of 3,875 bus miles and a sample standard deviation of 275 bus miles. Complete parts (a) and (b) below. Question content area bottom Part 1 a. Is there evidence that the population mean bus miles is more than 3,800 bus miles? (Use a 0.05 level of significance.) State the null and alternative hypotheses. The critical value(s) for the test statistic is(are) (Round to two decimal places as needed. Use a comma to separate answers as needed.)
In an effort to determine which company between Primacom Outsourcing Company and Technica Global Services has better customer service, an independent survey group gathered data on the length of time (in minutes) a customer has to wait on hold before someone answers the phone when calling the customer care hotline for assistance. The data is summarized below. Statistics Primacom Outsourcing Company Technica Global Services Mean 8.14 9.426 Standard Deviation 1.345 1.813 Sample Size 7 7 Is there a significant difference between the average lengths of time customers are on hold for the two companies? Use a 5% level of significance. Assume that the lengths of time on hold are normally distributed with unknown but equal population variances. A. Perform a complete test of hypothesis. B. Select here the conclusion for this test of hypothesis. There is a significant difference between the average lengths of time customers are on hold for the two companies. There is no significant difference…
You suspect that your east-facing portion of your Macintosh apple orchard is producing less apples than your west facing portion. You decide to conduct a study of your apple trees to determine the average production of apples per tree as measured in bushels for both sections. Conduct a hypothesis test at 5% level of significance to determine if the East facing section is producing significantly less apples per tree compared to the West facing section. Use the table below. Sample size Average amount of Standard of trees deviation Bushels West 55 28 East 50 22 12 What is the p-value? p=0.0021 0.025
Unoccupied seats on flights cause airlines to lose revenue. As an intern in the finance department for Sunrise Airways, Garrett is tasked with estimating the average number of unoccupied seats per flight over the past year. To accomplish this, the records of 320 flights are randomly selected and the number of unoccupied seats is noted for each of the sampled flights. The sample mean is 15.6 seats and the standard deviation is 4.6 seats. Construct a 99% confidence interval for the population mean number of unoccupied seats per flight during the past year. If necessary, round results to 1 decimal places.
Choose the appropriate statistical test. When computing, be sure to round each answer as indicated. A dentist wonders if depression affects ratings of tooth pain. In the general population, using a scale of 1-10 with higher values indicating more pain, the average pain rating for patients with toothaches is 6.8. A sample of 30 patients that show high levels of depression have an average pain rating of 7.1 (variance 0.8). What should the dentist determine? 1. Calculate the estimated standard error. (round to 3 decimals). [st.error] 2. What is thet-obtained? (round to 3 decimals). 3. What is the t-cv? (exact value) 4. What is your conclusion? Only type "Reject" or Retain"
when applying ANOVA which of the following steps would be important: a. the standard deviation of all the populations involved in the experiment is constant. b. the sample size of each sample is atleast 10. c. the population group that are being considerded are not more than 5. d. calculating side- by- side box plots will give a good visual representation of the variance between and within treatments. e. the samples are coming from normally distributed populations.
The void volume within a textile fabric affects comfort, flammability, and insulation properties. Permeability of a fabric refers to the accessibility of void space to the flow of a gas or liquid. An article gave summary information on air permeability (cm3/cm2/sec) for a number of different fabric types. Consider the following data on two different types of plain-weave fabric: Fabric Type Sample Size Sample Mean Sample Standard Deviation Cotton 10 51.41 0.75 Triacetate 10 132.15 3.59 Assuming that the porosity distributions for both types of fabric are normal, let's calculate a confidence interval for the difference between true average porosity for the cotton fabric and that for the acetate fabric, using a 95% confidence level. Before the appropriate t critical value can be selected, df must be determined: df = 0.5625 10 + 12.8881 10 2 (0.5625/10)2 9 + (12.8881/10)2 9 = 1.8092 0.1849…
