Assume that a simple random sample has been selected from a normally distributed population. Find the p-value, critical value(s), and state the final conclusion.
Test the claim that the mean age of a prison population in one city is less than 26 years. Sample data are summarized as n=25, x bar= 24.4 years, and s=9.2 years. Use significance level of 0.05
Find the p-value and the critical value(s)
test statistic: -0.8696
(except ice skater is replaced with prison population - amazingly, Google has shown that having 25 prisoner ice skaters is possible ..... I can Harding believe it ....).
