Hypothesis Testing Homework Help

I need homework help on problems 9, 10, 11, 23, and 24. I need tomorrow by 9:30 pm central time. See sample for layout show manual and      Stats Functional Work    

FYI-

You also need to know how to find P(Xbar>x)=P(Z>z*), P(Xbar<x)=p(z<z*), p(t="">t<x)=p(z<z*) from="" ch.="" 7,="" and="" how="" to="" find="" p(t="">t*), P(T>t) from Ch. 8.

Excel stats functions for p-values are =norm.dist, and =t.dist to find the p-values, and =norm.s.inv or =t.inv to find the critical values. To avoid rounding errors from the calculation of z*, e.g., from sqrt(50) in denominator, etc., your got z*=2.41489 and you rounded it to 2.41,please try to use norm.dist, not norm.s.dist(z*, true) to find the p-value; half of the credit will be taken away from the use of norm.s.dist.
