A newspaper published an article about a study in which researchers subjected laboratory gloves to stress. Among 202 vinyl gloves, 63% leaked viruses. Among 202 latex gloves, 11% leaked viruses. Using the accompanying display of the technology results, and using a 0.10 significance level, test the claim that vinyl gloves have a greater virus leak rate than latex gloves. Let vinyl gloves be population 1. Click the icon to view the technology results. What are the null and alternative hypotheses? C. Ho: P1 + P2 H1: P1 = P2 O A. Ho: P1 = P2 В.

Question Help Assume that we want to construct a confidence interval. Do one of the following, as appropriate: (a) find the critical value ta/2, (b) find the critical value za/2, or (c) state that neither the normal distribution nor the t distribution applies. 40 30- The confidence level is 95%, o is not known, and the histogram of 60 player salaries (in thousands of dollars) of football players on a team is as shown. 20- 10- 0- 4000 8000 12000 16000 20000 Salary (thousands of dollars). Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. ta/2= (Round to two decimal places as needed.) O B.

random sample of 50 binomial trials resulted in 20 successes. Test the claim that the population proportion of successes does not equal 0.50. Use a level of significance of 0.05. (a) Can a normal distribution be used for the distribution? Explain. No, n·q is greater than 5, but n·p is less than 5.Yes, n·p and n·q are both greater than 5. No, n·p is greater than 5, but n·q is less than 5.No, n·p and n·q are both less than 5.Yes, n·p and n·q are both less than 5. (b) State the hypotheses.

Constructing a Confidence Interval when the Population o is Unknown A pharmaceutical company makes tranquilizers. It is assumed that the distribution for the length of time they last is approximately normal but the population mean and standard deviation are not known. Researchers in a hospital used the drug on a random sample of nine patients. The sample mean was 2.51 hours. The sample standard deviation was 0.318. Work to construct a 95% confidence interval for the population mean by providing the following information. Useful tool: Student's t-Distribution Calculator (Include three decimal places below) а. а — b. v = c. to.025 d. EBM e. The lower bound of the Confidence Interval is f.
