Question

Question Help The accompanying data table lists the weights of male college students in kilograms. Test the claim that male college students have a mean weight that is less than the 83 kg mean weight of males in the general population. Use a 0.10 significance level. Identity the null hypothesis, alternative hypothesis, test statistic, P.value, and conclusion for the test. Assume this is a simple random sample Click the icon to view the sample data What are the null and alternative hypotheses? H1 : =83 kg HOP#83 kg H1:83 kg Calculate the test statistic. tRound to three decimal places as needed ) Identify the P-value The P-value is (Round to four decimal places as needed ) State the final conclusion that addresses the original claim Ho There is evidence to conclude that male college students have a mean weight that is less than the 83 kg mean weight of males in the general population

Explanation / Answer

Solution:

Option A is correct.

Null Hypothesis (Ho): µ = 83

Alternative Hypothesis (Ha): µ < 83

t = -5.699

P-value = 0.0000

Reject Ho. There is sufficient evidence to conclude that male college students have a mean weight that is less than the 83 kg mean weight of males in the general population.
