	a.	A 95% confidence interval for μ calculated from these data will not include μ = 8.
	b.	At the 5% level is H₀ is rejected, the probability of a Type II error is 0.034.
	c.	The 95% confidence interval for μ calculated from these data will be centered at μ = 8.
	d.	The null hypothesis should not be rejected at the 5% level.
	e.	The sample size is insufficient to draw a conclusion with 95% confidence.
