may I know how to solve this question a and d thank you 

d) With the assumption in (c), perform a hypothesis test to see whether the mean LDL cholesterol level of male adults who did not perform high intensity exercises in a 6-month period is lower higher than those who performed the exercises. Use the P-value approach at a = 0.05. Find the P-value by using the appropriate statistical table.

Use the P-value approach at a = 0.05. Find the P-value by using the appropriate statistical table.
There is a research on whether high intensity exercises can reduce the LDL cholesterol level of individuals. In the study, there are two groups of male adults (aged 18 or above). The first group is the control group and the second group is the intervention group. Participants in the control group did not perform any high intensity exercises in a 6-month period while participants in the intervention group performed a required amount of high intensity exercises in a 6-month period. The summary statistics of the LDL cholesterol levels (in mg/dL) of these two groups of participants are shown below. It can be assumed that the cholesterol levels of both groups follow the normal distribution. Group Control group Intervention group Sample Size 17 12 Mean 116 102 Standard deviation 18.1 19.4 a) A researcher claims the population mean LDL cholesterol level of male adults in the control group is greater than 110 mg/dL. Is there enough evidence to support the claim? Provide reasons by performing hypothesis test using the traditional method at the 5% significance level. Make sure the decision rule in the hypothesis test is stated clearly.
