1. The amount of the sample weights (in kilograms) of the random students athletes in Archangels school of arts is given each aspiring head of the research department.

2. Assume that the School's sports coordinator claims that the mean weight of all student-athletes is 52 kilograms with a standard deviation of 8 kilograms. Accomplish the following:

a. determine the sample mean weight of the seven randomly selected student- athlete (sample weights is up to you but one of the weight should be 52kg)

b. test the claim of the sports coordinator at 5% level of significance. Present the complete outcomes of each procedure in hypothesis testing:

i. formulate the null and alternative hypothesis

ii. Specify the level of significance and choose the appropriate statistical test. compute for the test statistic.

iii. establish the critical region

iv. make a decision and a conclusion

(base the mean and standard deviation of 8 from the weight 52kg)
