An panelist on a morning news program recently claimed that 32% of drivers routinely drive while distracted by their smartphones. A statistician happened to be watching this program, and decided to conduct a hypothesis test at the α=0.01α=0.01 level of significance to determine if this is accurate. (Round your results to three decimal places)Which would be correct hypotheses for this test? H0:p≠0.32H0:p≠0.32, H1:p=0.32H1:p=0.32 H0:p<0.32H0:p<0.32, H1:p=0.32H1:p=0.32 H0:p=0.32H0:p=0.32, H1:p<0.32H1:p<0.32 H0:p=0.32H0:p=0.32, H1:p>0.32H1:p>0.32 H0:p=0.32H0:p=0.32, H1:p≠0.32H1:p≠0.32 A random sample of 176 drivers resulted in 151 that routinely drive while distracted by their smartphones. Find the test statistic (2 decimals):Give the P-value (4 decimals):
The effectiveness of a new bug repellent is tested on 14 subjects for a 10 hour period. (Assume normally distributed population.) Based on the number and location of the bug bites, the percentage of surface area exposed protected from bites was calculated for each of the subjects. The results were as follows: x¯=93, ?=6 The new repellent is considered effective if it provides a percent repellency of at least 9090. Using ?=0.01, construct a hypothesis test with null hypothesis ?=90 and alternate hypothesis ?>90 to determine whether the mean repellency of the new bug repellent is greater than 9090 by computing the following: (a) the degrees of freedom (b) the test statistic

A refrigerator manufacturer claims that the mean life of its refrigerators is greater than 13 years. You are asked to perform a hypothesis test to test this claim. (a) How would you write the null and alternative hypothesis if you represent the manufacturer and want to support the claim? (b) How would you write the null and alternative hypothesis if you represent the competitor and want to reject the claim?
