11 In a survey of 100 males and 100 females at a regional university, 26 percent of the males and 18 percentof the females responded that they were offended by frequently aired television. The test question is:а).What is the calculated value of the test statistic?b).At a significance level of 0.01, what will be he critical value for this test?с).Could these results indicate that the same proportions of the two samples are offended? Explain.

Since an instant replay system for tennis was introduced at a major tournament, men challenged 1392 referee calls, with the result that 421 of the calls were overturned. Women challenged 754 referee calls, and 212 of the calls were overturned. Use a 0.05 significance level to test the claim that men and women have equal success in challenging calls. a. Identify the test statistic. z equals (Round to two decimal places as needed.) b. Identify the P-value. P-value equals (Round to three decimal places as needed.) c. Test the claim by constructing an appropriate confidence interval. The 95% confidence interval is less than left parenthesis p 1 minus p 2 right parenthesis less than (Round to three decimal places as needed.)
A computer manufacturer believes that the proportion of hardware malfunctions is different in humid climates than in dry climates. To test this claim, the manufacturer takes a random sample of 400 machines sold in Florida (humid) and 400 machines sold in Arizona (dry). The manufacturer finds that 44 of the machines in Florida and 24 of the machines in Arizona had hardware malfunctions. Compute the p-value. Does the evidence support the computer manufacturer's claim at the 10% significance level?
In a simple random sample of 26 small business owners, 25 said that hiring college graduates makes their workplace better. Test the hypothesis that more than 81% of small business owners believe that hiring college graduates makes their workplace better at the 0.05 level. What is the alternative hypothesis? What is the appropriate critical value? State your decision given a test statistic of 1.3.
A newspaper published an article about a study in which researchers subjected laboratory gloves to stress. Among 273 vinyl gloves, 64% leaked viruses. Among 273 latex gloves, 6%leaked viruses. Using a 0.01 significance level, test the claim that vinyl gloves have a greater virus leak rate than latex gloves. Let vinyl gloves be population 1. 1. Test statistic 2. P-value 3. What is the conclusion for this test?
In a random sample of males, it was found that 25 write with their left hands and 217 do not. In a random sample of females, it was found that 58 write with their left hands and 450 do not. Use a .05 significance level to test the claim that the rate of left-handedness among males is less than that among females. Identify the test statistic.z=?
According to the U.S. Census Bureau, 11% of children in the United States lived with at least one grandparent in 2009 (USA TODAY, June 30, 2011). Suppose that in a recent sample of 1600 children, 237 were found to be living with at least one grandparent. At a 5% significance level, can you conclude that the proportion of all children in the United States who currently live with at least one grandparent is higher than 11%? Use both the p-value and the critical-value approaches. Round your answers for the observed value of z and the critival value of z to two decimal places, and the p-value to four decimal places.zobserved =Enter you answer; z_observed p-value =Enter you answer; p-value Critical value =Enter you answer; Critical value

Since an instant replay system for tennis was introduced at a major tournament, men challenged 1415 referee calls, with the result that 419 of the calls were overturned. Women challenged770 referee calls, and 225 of the calls were overturned. Use a 0.05 significance level to test the claim that men and women have equal success in challenging calls. A. Identify the test statistic. z equals (Round to two decimal places as needed.) B. Identify the P-value. P-value equals (Round to three decimal places as needed.) C. Test the claim by constructing an appropriate confidence interval. The 99% confidence interval is less than left parenthesis p 1 minus p 2 right parenthesis less than .

A random sample of 100 people from region A and a random sample of 100 people from region B were surveyed about their grocery-shopping habits. From the region A sample, 16 percent of the people indicated that they shop for groceries online. From the region B sample, 24 percent of the people indicated that they shop for groceries online. At the significance level of α=0.05, do the data provide convincing statistical evidence that there is a difference between the two regions for the population proportions of people who shop online for groceries? Complete the appropriate inference procedure to support your answer.
According to the American Diabetes Association,23.1% of Americans aged 60 years or older haddiabetes in 2007. A recent random sample of 200Americans aged 60 years or older showed that 52 ofthem have diabetes. Using a 5% significance level,perform a test of hypothesis to determine if thecurrent percentage of Americans aged 60 years orolder who have diabetes is higher than that in 2007.
A computer manufacturer believes that the proportion of hardware malfunctions is different in humid climates than in dry climates. To test this claim, the manufacturer takes a random sample of 400 machines sold in Florida (humid) and 400 machines sold in Arizona (dry).

In a preliminary study, the U.S. Veterans Affairs Department found that 20.9% of the 81 soldiers who were near an accidental nerve gas release just after the 1991 Persian Gulf War had muscle and bone ailments, compared to a rate of 15.5% for the 52,000 Gulf veterans who were not near that area. Use an appropriate test and the 0.10 level of signi?cance in examining if there is significance difference between these two rates. Select one: a. The Null hypothesis that two rates are not different is rejected as p-value=0.07 is less than 0.10 b. The Difference between two rates is not significant as p-value=0.17 and is more than alpha=0.10 c. The Alternative hypothesis that two proportions are not equal is accepted as p-value=0.09 and is less than 0.1 d. The Alternative hypothesis that two proportions are equal is rejected as p-value=0.14 and is more than alpha=0.1
