A company that produces and markets video game systems wishes to assess its customers level of satisfaction with a relatively new model, the XYZ-Box. In the six months since the introduction of the model, the company has received 73,219 warranty registrations from purchasers. The company will select a random sample of 65 of these registrations and will conduct telephone interviews with the purchasers. Specifically, each purchaser will be asked to state his or her level of agreement with each of the seven statements listed on the survey instrument given in the following table.

The Video Game Satisfaction Survey Instrument
	Strongly						Strongly
Statement	Disagree						Agree
The game console of the XYZ-Box is well designed.	1	2	3	4	5	6	7
The game controller of the XYZ-Box is easy to handle.	1	2	3	4	5	6	7
The XYZ-Box has high quality graphics capabilities.	1	2	3	4	5	6	7
The XYZ-Box has high quality audio capabilities.	1	2	3	4	5	6	7
The XYZ-Box serves as a complete entertainment center.	1	2	3	4	5	6	7
There is a large selection of XYZ-Box games to choose from.	1	2	3	4	5	6	7
I am totally satisfied with my XYZ-Box game system.	1	2	3	4	5	6	7

Here, the level of agreement for each statement is measured on a 7-point Likert scale. Purchaser satisfaction will be measured by adding the purchasers responses to the seven statements. It follows that for each consumer the minimum composite score possible is 7 and the maximum is 49. Furthermore, experience has shown that a purchaser of a video game system is very satisfied if his or her composite score is at least 42. Suppose that when the 65 customers are interviewed, their composite scores are as given in the following table.

Composite Scores for the Video Game Satisfaction Rating Case
37	37	17	33	43
40	43	30	43	25
27	38	45	42	32
33	20	46	24	45
34	18	37	16	25
24	35	22	26
15	22	21	45
42	36	31	40
31	25	19	28
17	39	45	44
35	40	18	35
25	36	22	35
26	46	41	40
16	27	29	23
35	27	36	24

Using the data, estimate limits between which most of the 73,219 composite scores would fall. Also, estimate the proportion of the 73,219 composite scores that would be at least 42.(Round your proportion of scoresanswer to 3 decimal places.)

Most of the scores would fall between____and_____

An estimate of the proportion of scores that would be at least 42 =
