Hi there, I have been marked wrong on an assignment performing hypotheses tests and find the p-value for the tests. I was hoping you could let me know where I went wrong.

The tests are:

Ho: mean= 255

Ha: mean255

n=25

standard deviation=12

xbar=252

95% significance

My answer here is that T*=-1.25 and P(T

The other test is:

Ho: mean <= 125.65

Ha: mean > 125.65

n=9

s.d=90

xbar=126

95% confidence

My answer is : T*=0.012 p(T

Thank you!
