Consider the normal distribution with unknown mean and unknown variance 2, and suppose that it is

Question:

Consider the normal with unknown mean μ and unknown variance σ2, and suppose that it is desired to test the following hypotheses:
H0: μ ≤ μ0,
H1: μ>μ0.
Suppose that it is possible to observe only a single value of X from this but that an independent random sample of n observations Y1, . . . , Yn is available from the normal with known mean 0 and the same variance σ2 as for X. Show how to carry out a test of the hypotheses H0 and H1 based on the t with n degrees of freedom. Distribution
The word "distribution" has several meanings in the financial world, most of them pertaining to the payment of assets from a fund, account, or individual security to an investor or beneficiary. Retirement account distributions are among the most...
