Question

Suppose you are testing the null hypothesis that the population mean is less than or equal to 80, against the alternative hypothesis that the population mean is greater than 80. The sample size is 49 and alpha. If the sample mean is 84 and the population standard deviation is 14, the observed value is.

Step 1

Step 1: Calculate the z-score using the formula z = (x_bar - mu) / (sigma / sqrt(n)), where x_bar = 84, mu = 80, sigma = 14, and n = 49. Show more…
