A company surveyed 2300 men where 1104 of the men identified themselves as the primary grocery shopper in their household.

?a) Estimate the percentage of all males who identify themselves as the primary grocery shopper. Use a 98?% confidence interval. Check the conditions first.

?b) A grocery store owner believed that only 43?% of men are the primary grocery shopper for their?family, and targets his advertising accordingly. He wishes to conduct a hypothesis test to see if the fraction is in fact higher than 43?%. What does your confidence interval?indicate? Explain.

a) Check the conditions for constructing a confidence interval. Select all necessary conditions that have the appropriate explanation below. A. Randomization Condition: This condition is not satisfied because the samples were drawn from a convenience sample. B. Success/Failure Condition: This condition is satisfied because there were more than 10 successes and failures. C. Randomization Condition: This condition is satisfied because there is nothing to indicate that the samples were not drawn randomly. D. 10% Condition: This condition is satisfied because 2300 men are less than 10% of the population of men. E. Success/Failure Condition: This condition is not satisfied because there were fewer than either 10 successes or failures. OF. Nearly Normal Condition: This condition is not satisfied because it is highly unlikely that the population of men is Normal. G. Nearly Normal Condition: This condition is satisfied because there is nothing to indicate that the underlying population is not Normal. H. 10% Condition: This condition is not satisfied because 2300 men are more than 10% of the population of men
