Question

How likely is it that a randomly selected consumer in the survey purchased the product? (Round answer to 2 decimal places, e.g. 52.22.)

Section Exercise 4.49 A questionnaire concerning the effect of a recent advertising campaign was sent out to a sample of 570 consumers. Results of the study are reported in the cross-tabulation table below: Saw Didn't Total Ad See Ad 130 Purchased Didn't Purchase 100 Total 50 180 290 390 340 570 230 (al) Your answer is correct. Convert the table to a joint probability table. (Round answers to 2 decimal places, e.g. 52.22.) Saw Ad Didn't See Ad Total Purchased 23 09 32 Didn't Purchase 18 51 68 Total 40 60

Explanation / Answer

From the given information

The total number of consumers who purchased the product = 180

Total number of consumers = 570

So, if a consumer selected randomly

Then the probability of he/she is purchased the product is 180/570 = 0.315789 = 0.32

(Or 180C1/570C1 = 180/570 = 0.32)
