Answer 1

d)

P(individual is a male who gives the phrase rating of 4)

e)

P(individual is a 35 to 49 year old who gives the phrase rating of 1)

Required probability = P(individuals surveyed who recalled seeing the advertisement had purchased Fresh)

= P(individuals had purchased Fresh | individual was recalled seeing the advertisement)

= P(individuals had purchased Fresh and individual was recalled seeing the advertisement) / P(individual was recalled seeing the advertisement)

= 0.15 / 0.45

= 0.333
