Before distributing an ad campaign nationally, an advertising company plans to show the commercial to a random sample of 15 people. It will also show the same people two additional commercials for different products or businesses. Complete parts a through c. a. Assuming that the advertisement will be successful (83% will be able to recall the name of the company in the ad), what is the expected number of people in the sample who will recall the company featured in the commercial one hour after viewing the three commercials? The expected number of people is 12.45. (Type an integer or a decimal. Do not round.) b. Suppose that in the sample of 15 people, 9 were able to recall the name of the company in the commercial one hour after viewing.

advertising company plans to show the commercial to a random
sample of 15 people. It will also show the same people two additional
commercials for different products or businesses. Complete parts a
through c.
a. Assuming that the advertisement will be successful (83% will be able
to recall the name of the company in the ad), what is the expected
number of people in the sample who will recall the company featured in
the commercial one hour after viewing the three commercials?
The expected number of people is 12.45.
(Type an integer or a decimal. Do not round.)
