A nutritionist claims that the mean tuna consumption by a person is 3.2 pounds per year. A sample of 60 people shows that the mean tuna consumption by a person is 3.1 pounds per year. Assume the population standard deviation is 1.22 pounds. At a = 0.05, can you reject the claim? (a) Identify the null hypothesis and alternative hypothesis. O A. Ho: H # 3.1 O B. Ho: HS3.2 O C. Ho: H > 3.1 Ha: H = 3.1 Ha: H > 3.2 Ha: HS 3.1 O D. Ho: HS3.1 O E. Ho: H= 3.2 OF. Ho: H > 3.2 Ha: H > 3.1 Ha: H # 3.2 Ha: HS 3.2 (b) Identify the standardized test statistic. z= (Round to two decimal places as needed.) (c) Find the P-value. (Round to three decimal places as needed.) (d) Decide whether to reject or fail to reject the null hypothesis. O A. Reject Ho. There is sufficient evidence to reject the claim that mean tuna consumption is equal to 3.2 pounds. O B. Fail to reject Ho. There is not sufficient evidence to reject the claim that mean tuna consumption is equal to 3.2 pounds O C. Reject Ho. There is not sufficient evidence to reject the claim that mean tuna consumption is equal to 3.2 pounds. O D. Fail to reject Ho. There is sufficient evidence to reject the claim that mean tuna consumption is equal to 3.2 pounds.A consumer group claims that the mean minimum time it takes for a sedan to travel a quarter mile is greater than 14.7 seconds. A random sample of 22 sedans has a mean minimum time to travel a quarter mile of 15.3 seconds and a standard deviation of 2.09 seconds. At a = 0.05 is there enough evidence to support the consumer group's claim? Complete parts (a) through (d) below. Assume the population is normally distributed. (a) Identify the claim and state Ho and Ha- Ho Ha. (Type integers or decimals. Do not round.) The claim is the hypothesis. (b) Use technology to find the P-value. Find the standardized test statistic, t. t= (Round to two decimal places as needed.) Obtain the P-value. P =0 (Round to three decimal places as needed.) (c) Decide whether to reject or fail to reject the null hypothesis. Ho because the P-value greater than a. (d) Interpret the decision in the context of the original claim.
