A researcher who wants to know whether the proportion of male births in a hospital is different from the established baseline of 51.07%, would like to test the following hypotheses: Ho:P = 0.51 vs. Ha :P = does not equal 0.51 a) Is the alternative hypothesis upper tail, lower tail, or two tailed? b) What do you conclude if the test results p-value of 0.03 at alpha value = 5% c) What do you conclude if the test results p-value of 0.08 at alpha value = 10%
Ex 9. Suppose that a national survey finds that 73 percent of restaurant employees say that work stress has a negative impact on their personal lives. A random sample of 200 employees of a large restaurant chain finds that 141 employees say that work stress has a negative impact on their personal lives. a. Formulate the null and alternative hypotheses needed to attempt to provide evidence that the percentage of work-stressed employees for the restaurant chain differs from the national percentage. b. Use critical values to perform the hypothesis test by setting α equal to .10, .05, .01, and .001

For the following pairs, indicate which do not comply with the rules for setting up hypotheses, and explain why. (Select all that apply.) (a) H0: ? = 16, Ha: ? = 16 This pair complies.This pair does not comply because ? is not a population characteristic.This pair does not comply because both hypotheses use an equal sign.This pair does not comply because the two hypotheses use different numbers. (b) H0: p = 0.5, Ha: p > 0.8 This pair complies.This pair does not comply because p is not a population characteristic.This pair does not comply because both hypotheses use an equal sign.This pair does not comply because the two hypotheses use different numbers.

The recommended daily dietary allowance for zinc among males older than age 50 years is 15 mg/day. An article reports the following summary data on intake for a sample of males age 65−74 years: n = 116, x = 12.5, and s = 6.35. Does this data indicate that average daily zinc intake in the population of all males age 65−74 falls below the recommended allowance? (Use ? = 0.05.)State the appropriate null and alternative hypotheses. H0: ? = 15Ha: ? ≠ 15H0: ? = 15Ha: ? > 15 H0: ? = 15Ha: ? ≤ 15H0: ? = 15Ha: ? < 15 Calculate the test statistic and determine the P-value.

The records of a casualty insurance company show that, in the past, its clients have had a mean of 1.9auto accidents per day with a standard deviation of 0.04 . The actuaries of the company claim that the standard deviation of the number of accidents per day is no longer equal to 0.04 . Suppose that we want to carry out a hypothesis test to see if there is support for the actuaries' claim. State the null hypothesis H0 and the alternative hypothesis H1 that we would use for this test. H0 : ? H1 : ?
The records of a casualty insurance company show that, in the past, its clients have had a mean of 1.8auto accidents per day with a standard deviation of 0.06.

A p-value of 0.02 means that you must: a. Reject the null hypothesis b. Accept the null hypothesis c. Go back to the drawing board because you shouldn’t get a result higher than 0.05 d. Recode your data so you make sure to get statistically significant results
A city police department is considering replacing thetires on its cars with a new brand tires. If μ1 is the average number of miles that the old tires last and μ2 is the aver-age number of miles that the new tires will last, the null hypothesis to be tested is μ1 = μ2.(a) What alternative hypothesis should the departmentuse if it does not want to use the new tires unless theyare definitely proved to give better mileage? In otherwords, the burden of proof is put on the new tires, andthe old tires are to be kept unless the null hypothesis canbe rejected.(b) What alternative hypothesis should the departmentuse if it is anxious to get the new tires unless they actuallygive poorer mileage than the old tires? Note that now theburden of proof is on the old tires, which will be kept onlyif the null hypothesis can be rejected.(c) What alternative hypothesis should the departmentuse so that rejection of the null hypothesis can leadeither to keeping the old tires or to buying the newones?
