Description: A data set includes data from student evaluations of courses. The summary statistics are n = 97, x = 3.59, s = 0.58. Use a 0.10 significance level to test the claim thatthe population of student course evaluations has a mean equal to 3.75. Assume th

The provided information are: Sample size (n) = 97Sample mean(x¯)=3.59Sample standard deviation(s)=0.58The hypotheses are: H0:μ=3.75H1:μ≠3.75 The correct option is (c) Here, sample standard standard deviation is known. Thus, t-test statistic is to be computed. t=x¯-μsn=3.59-3.750.5897=-2.72 Thus, the test statistic is -2.72.The degree of freedom is: Degree of freedom = Sample size -1 = 97-1 = 96 The p-value could be calculated as: P-value=2×P(t>|t|)=2×P(t>|-2.72|)=0.008 The P-value is 0.008.Decision rule: The null hypothesis is rejected if P-value is less than the significance level. Here, P-value (0.008)<α0.10 The null hypothesis is rejected Conclusion: Reject Ho. There is enough evidence to conclude that the original claim that the mean of the population of student course evaluation is equal to 3.75 is not correct.
