Question: A random sample of n = 50 observations from a quantitative population produced a mean x = 2.6 and a standard deviation s = 0.35.

A random sample of n = 50 observations from a quantitative population produced a mean

x = 2.6

and a standard deviation

s = 0.35.

Your research objective is to show that the population means exceeds 2.5. Do the data provide sufficient evidence to conclude that > 2.5? (Use a 5% significance level.)
