Question 22. Question 23.

Question 24.marketing researcher surveyed 94individuals, asking them if they liked a new product concept or not. The results are shown in the accompanying table. Convert the data into percentages for each gender class. Then construct a chart of the counts and a chart of the percentages. Discuss what each conveys visually and how the different charts may lead to different interpretations of the data.

	Yes	No
Male	30	46
Female	9	9

Discuss what each conveys visually and how the different charts may lead to different interpretations of the data.

A.

While both charts show that fewer females liked the product than dislikedit, the first chart may be misleading as it suggests that females either like or dislike the product more thanmales, simply because of the differences in the number of responses. The count chart shows the relative proportions better because they are independent of the response differences.However, the first chart shows the overall"no" preference more clearly due to the smaller number of male responses.

B.

While both charts show that fewer males liked the product than dislikedit, the first chart may be misleading as it suggests that males either like or dislike the product more thanfemales, simply because of the differences in the number of responses. The percentage chart shows the relative proportions better because they are independent of the response differences.However, the first chart shows the overall"no" preference more clearly due to the smaller number of female responses.

C.

While both charts show that fewer females liked the product than dislikedit, the first chart may be misleading as it suggests that females either like or dislike the product more thanmales, simply because of the differences in the number of responses. The percentage chart shows the relative proportions better because they are independent of the response differences.However, the first chart shows the overall"yes" preference more clearly due to the smaller number of male responses.

Question 37.The historical data of VelvettaInc., a healthcare productsmanufacturer, have shown that in a production process for filling bottles ofshampoo, variance in the volume isconstant; however, clogs in the filling machine often affect the mean volume. The historical standard deviation is 5 milliliters. In filling250-milliliter bottles, a sample of 20 found a mean volume of 242 milliliters. From thetable, determine the cumulative probability for z at a95% confidence level. Round to three decimal places.
