Asked by Mary
Given a sample size of 18, with sample mean 660.3 and sample standard deviation 95.9 we are to perform the following hypothesis test.
Null Hypothesis H0: ƒÊ = 700
Alternative Hypothesis H0: ƒÊ ‚ 700
At significance level 0.05
1. What is the critical value for this test? Calculate the test statistics.
2. Do we reject the Null Hypothesis? (explain why)

Is your symbol, ƒÊ = μ = mean?
Ho: μ = 700
H1: μ ≠ 700
For P = .05, need μ ± 1.96 SE
SE = SD/√(n-1)
I hope this helps.
