Consider the hypotheses shown below. Given that
x̅=61,
σ=15,
n=42,
α=0.05,
complete parts a and b.
Ho: μ ≤ 57
H1: μ > 57
a. What conclusion should be drawn?
b. Determine the p-value for this test.
Friendly Note: This is an example. For Part a, the answer is Z x̅ = 1.73 and Z α = 1.64 For Part b, the p-value is 0.042.
I just want to know 2 things.
1) How do you find Z α ?! I tried everything but no luck.
2) I understand how to find Z x̅ with the formula, but how would you solve all of the parts a and b with excel? Please go into detail!
