Based on a random sample of size 43, a 93% confidence interval for was found to be (24.6, 28.38). This interval will be used to test the following hypotheses: Ho:= 22.3 Ha: 22.3 (a) What is the conclusion? O Do not reject the null hypothesis. 22.3 is in the interval, and therefore is one of the plausible values for μ, according to this confidence interval. Reject the null hypothesis. 22.3 is not in the interval, and therefore is not one of the plausible values for μ, according to this confidence interval. O Do not reject the null hypothesis. 22.3 is not in the interval, and therefore is not one of the plausible values for μ, according to this confidence interval. O Reject the null hypothesis. 22.3 is in the interval, and therefore is one of the plausible values for μ, according to this confidence interval. (b) What is the significance level of the test? (2 decimal places) (c) How many degrees of freedom are associated with this confidence interval? [ (whole number)
