H0: μ=60 seconds H1: μ>60 seconds D. H0: μ≠60 seconds H1: μ=60 seconds Determine the test statistic. (Round to two decimal places as needed.) Determine the P-value. (Round to three decimal places as needed.)The label on a 4-quart container of orange juice states that the orange juice contains an average of 1 gram of fat or less. Answer the following questions for a hypothesis test that could be used to test the claim on the label. (a) Develop the appropriate null and alternative hypotheses.

Find the test statistic (Round to 2 decimals):Give the P-value (Round to 4 decimals - if less than 0.001 give answer as 0):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 statisticThe effectiveness of a new bug repellent is tested on 25 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: ?⎯⎯⎯=93, ?=12 The new repellent is considered effective if it provides a percent repellency of at least 91. Using ?=0.05, construct a hypothesis test with null hypothesis ?=91 and alternate hypothesis ?>91 to determine whether the mean repellency of the new bug repellent is greater than 91 by computing the following: (a) the degrees of freedom (b) the test statistic The final conclusion is A. We can reject the null hypothesis that ?=91. Our results indicate that the new bug repellent is effective.B. There is not sufficient evidence to reject the null hypothesis that ?=9. Our results do not provide enough evidence that the new bug repellent is effective.
