B. Critical Values
C. P value and interpret the result
Answer within 15 minutes
Economists theorize that the recent recession has affected men more than women because mon are typically employed in industries that have been hit hardest by the recession Women, on the other hand, are typically employed in services which are considered more recession resistant. A sample of 170 men and a sample of 145 women were drawn. In those samples, 21 men were unemployed, and 11 of...
