adell [148]

Answer:

There is no statistical evidence to support the claim that the mean is elss than 74.

Step-by-step explanation:

Given that a paint-drying situation in which drying time for a test specimen is normally distributed with s = 6.

The hypotheses H0: µ = 74 and Ha: µ < 74

are to be tested using a random sample of n = 25 observations

a) Z = $\frac{72.3-74}{\frac{6}{\sqrt{25} } } \\=-1.417$

ie. -1.417 std deviations to the left of mean.

b) p value = 0.078241

Since p > 0.01 , our alpha, accept H0

There is no statistical evidence to support the claim that the mean is elss than 74.
