Question

In a random sample, the weights of 24 Black Angus
steers of a certain age have a standard deviation of 238
pounds. Assuming that the weights constitute a random
sample from a normal population, test the null hypothesis
σ = 250 pounds against the two-sided alternative σ Z 250
pounds at the 0.01 level of significance.
