Question

Suppose we are testing the null hypothesis H0: u = 20 and the alternative Ha: u (not equal to) 20, for a normal population with o = 5. A random sample of 25 observations are drawn from the population, and we find the sample mean of these observations is x-bar= 16.7. The P-value is closest to 0.0012 0.0024 .0164 .2546

Step 1

Step 1: Compute the standard error of the mean - sigma = 5, n = 25, so standard error = sigma / sqrt(n) = 5 / sqrt(25) = 5 / 5 = 1. Show more…
