Please help me with a,b,cC. Based on your answer to part (b), choose what the administrator can conclude, at 0.10 level of significance. Is the p value less than or greater than the level of significance? Is there enough evidence to conclude that the mean distance hiked by each visitor is now less than 21 kilometers?

Becauseof this, an administrator at the park suspects the mean distance, µ, is now less than 21 kilometers. The administrator chooses arandom sample of 85 visitors. The mean distance hiked for the sample is 19.1 kilometers. Assume the population standard deviationis 9.1 kilometers.Can the administrator conclude that the mean distance hiked by each visitor is now less than 21 kilometers? Perform a hypothesistest, using the 0.10 level of significance.(a) State the null hypothesis H and the alternative hypothesis H,.Ho: 0OOH: 0O20D=0(b) Perform a Z-test and find the p-value.Here is some information to help you with your Z-test.
