Given
This is a one-tailed test.
Since the p-value of the sample statistic (0.00383) is less that the significant level (0.025), we reject the null hypothesis.

Suppose that you are to conduct the following hypothesis test: H0:H1:μ μ=≠510510H0:μ=510H1:μ≠510 Assume that you know that σ=90σ=90, n=42n=42, x=487.5x¯=487.5, and take α=0.1α=0.1. Draw the sampling distribution,

A test is made of H0 : μ = 47 versus H1 : μ > 47. A sample of size n=69 is drawn, and x=48. The population standard deviation is σ=27. Compute the value of the test statistic z.
