Question

Suppose a left-tailed hypothesis test for a mean is conducted. The test statistic for the hypothesis test was calculated to be -2.38, derived from a sample of size 37. Determine the correct conclusion, given the result above. Assume the population standard deviation is known. Let ? = 0.02. ? Fail to reject H0 ? Reject H0 ? Reject H1 ? Fail to reject H1 Interpret the above conclusion. ? The sample data provide sufficient evidence to reject the alternative hypothesis and conclude that the null hypothesis is likely true. ? The sample data do not provide sufficient evidence to reject the null hypothesis and conclude that the null hypothesis is likely true. ? The sample data do not provide sufficient evidence to reject the alternative hypothesis and conclude that the alternative hypothesis is likely true. ? The sample data provide sufficient evidence to reject the null hypothesis and conclude that the alternative hypothesis is likely true.
