H0:μ=16.87H1:μ>16.87 Your sample consists of 46 subjects, with a mean of 17.9 and standard deviation of 4.26.Calculate the test statistic, rounded to 2 decimal places. t=

You want to obtain a sample to estimate a population mean. Based on previous evidence, you believe the population standard deviation is approximately σ=62.5σ=62.5. You would like to be 95% confident that your estimate is within 1.5 of the true population mean. How large of a sample size is required? Round up to nearest whole number.

nutritionist claims that the mean tuna consumption by a person is 3.4 pounds per year. A sample of 90 people shows that the mean tuna consumption by a person is 3.3 pounds per year. Assume the population standard deviation is 1.02 pounds. At α=0.03​, can you reject the​ claim?       ​(a) Identify the null hypothesis and alternative hypothesis.     A. H0​: μ=3.4 Ha​: μ≠3.4 Your answer is correct.   B. H0​: μ>3.4 Ha​: μ≤3.4   C. H0​: μ≤3.3 Ha​: μ>3.3   D. H0​: μ≤3.4 Ha​: μ>3.4   E. H0​: μ>3.3 Ha​: μ≤3.3   F. H0​: μ≠3.3 Ha​: μ=3.3 ​(b) Identify the standardized test statistic.   z=negative 0.93−0.93 ​(Round to two decimal places as​ needed.) ​(c) Find the​ P-value.   0.3520.352 ​(Round to three decimal places as​ needed.) ​(d) Decide whether to reject or fail to reject the null hypothesis.
