We are testing H₀: ? ? 2.5;versus H_A: ?

Question

We are testing H₀: ? ? 2.5;versus H_A: ? < 2.5.When

\bar { X } = 2.46

s = .05,and n = 26,at ? = .10 we reject the null hypothesis.(Assume that the population from which the sample is selected is normally distributed. )

Quizplus · Accepted Answer

Since the null hypothesis is rejected at α = 0.10, we can conclude that the sample mean is significantly smaller than the hypothesized population mean of μ ≥ 2.5 at the 10% level of significance. Therefore, the statement "we reject the null hypothesis" is true.

We Are Testing H0: ? ? 2 Xˉ=2.46\bar { X } = 2.46Xˉ=2.46

We Are Testing H₀: ? ? 2 $\bar { X } = 2.46$
