A company is about to introduce a new product in the market. It asked a number of people to indicate the likelihood of purchasing the product.

Code: Likelihood of purchase:

Very likely = 5; Likely= 4; Undecided = 3;

Unlikely = 2; Very unlikely = 1

Gender: Male = 1; Female = 2

Q 3(b). Interpret the histogram and support your conclusions using the descriptive statistics.

Q.4

At almost every university in the U.S.A. and in other countries with similar education system such as Kuwait, the universities compute student GPA using the following scale
A = 4 points, B = 3 points, C = 2 points, D = 1 point, and F = 0 point.

Question 4

(a) Discuss what, if any, problems might exist when GPAs for two students are compared within the same university?

(b) What about comparing GPAs for students from two different universities?

(C) What statistic do you suggest to provide additional information.

Q5 Given the cross tabulation below calculate the relative frequencies

Income (000)	No college	1-2 year college	3-4 year	5-6 years	> 6 years
$20 <	16	33	30	6	4	89.00
$20 < $40	22	28	40	26	5	121.00
$40 < $60	9	12	21	46	9	97.00
$60 >	3	5	15	13	6	42.00
Total	50	78	106	91	24	349

Question 5

Q 5 (a): Determine the % of those with at least 5 years of college than earn at least $40,000

Q 5 (b):Compare the proportion of Q(a) to the proportion for those having fewer than 5 years of college. What conclusion can you draw?

Q 5 (c): Determine the % of those who make at least $60,000 and who have more than 4 years of college

Q 5 (d) Draw an overall conclusion from the data and the calculations performed.
