Thank you Dason. Sorry about that. Ive done 2 parts to the question so far.

First being: Choose the correct statistical hypotheses.

A. H0:X⎯⎯⎯=22,HA:X⎯⎯⎯≠22

B. H0:X⎯⎯⎯>22.49,HA:X⎯⎯⎯≤22.49

C. H0:X⎯⎯⎯=22,HA:X⎯⎯⎯>22

D. H0:X⎯⎯⎯=22.49,HA:X⎯⎯⎯>22.49

E. H0:μ=22HA:μ>22

F. H0:μ=22,HA:μ≠22

G. H0:μ>22,HA:μ<22

Which I found to be D

And (d) Suppose the statistician decides to change the sample size to n=200 and regulate P(TypeI)=0.05. For what values of X⎯⎯⎯ should the null hypothesis in (a) be rejected?

A. Reject the null hypothesis if X⎯⎯⎯>22.29

B. Reject the null hypothesis if X⎯⎯⎯>22.00

C. Reject the null hypothesis if X⎯⎯⎯>22.50

D. Reject the null hypothesis if μ>22.50

E. Reject the null hypothesis if μ>22.29

F. Reject the null hypothesis if X⎯⎯⎯>22.49

Which I calculated was B. Im just not sure how to go about finding the probability of a type I error

I got an answer of .950 for the probabilty of a type I error. Which does not seem correct.

And I got .002 for part c)
