A technical engineer is interested in understanding the battery life of two different laptops for student usage at a community college in California. The two models he has are Madroid and Krapple. He randomly assigned students to one of the laptop models and recorded the number of minutes the students were able to use the computer until the battery ran out. Below is the data collected.

Student # Madroid Krapple
1 540 575
2 380 525
3 420 583
4 480 680
5 530 628
6 467 680
7 465 640
8 498 630
9 482 725
10 309 780
11 609 530
12 540 280
13 580 350
14 433 376
15 640 540

Does the technical engineer have statistically significant evidence to present to the university budget committee to purchase Krapple because it has, on average, a longer battery life?

Provide the p-value from your analysis.

Solutions

Expert Solution

From the given data

(1) Null and Alternative Hypothesis:

H0: Krapple batter life is  on average, is not  longer than Madroid battery life

H1: Krapple batter life is  on average, is longer than Madroid battery life

i.e.

Thus we conclude that Krapple batter life is  on average, is not longer than Madroid battery life

A grocery store was interested in understanding the level of brand loyalty for different products. The store randomly polled 100 customers who had just purchased milk and found that, of the 100 customers, 53 were loyal to one brand of milk. The store then randomly polled 100 customers who had just purchased bath soap and found that, of the 100 customers, 65 were loyal to one brand of soap. The grocery store would like to know if this shows evidence...
