Pay Workdays at Home each Week Short of what One At any rate One, however Not All at Home Under $25,000 38 16 14 $25,000$49,999 54 26 12 $50,000$74,999 35 22 9 Above $75,000 33 29 12

a. Do the information introduce adequate proof to demonstrate that compensation is reliant on the quantity of workdays spent at home? Test utilizing a = .05. b. Utilize Table 5 in Index Ito surmised the p-an incentive for this trial of theory. Does the p-esteem affirm your determinations from section a?

Question 86

Irregular examples of 200 perceptions were chosen from every one of three populaces, and every perception was arranged by whether it could be categorized as one of three totally unrelated classes:

Classification

Populace 1 2 3 All out 1 108 52 40 200 2 87 51 62 200 3 112 39 49 200

You need to know whether the information give adequate proof to show that the extents of perceptions in the three classes rely upon the populace from which they were drawn. a. Give the estimation of x2 for the test. b. Give the dismissal locale for the test for a = .01. c. Express your decisions. d. Track down the estimated p-an incentive for the test and decipher its worth.

Question 87

Assume you wish to test the invalid theory that three binomial boundaries Dad, pn, and pc are equivalent versus the elective speculation that at any rate two of the boundaries vary. Free irregular examples of 100 perceptions were chosen from every one of the populaces. The information are appeared in the table.

Populace A B C Aggregate

Victories 24 19 33 76 Disappointments 76 81 67 224 Complete 100 300

a. Compose the invalid and elective speculations for testing the balance of the three binomial extents. b. Compute the test measurement and track down the rough p-an incentive for the test to some degree a. c. Utilize the estimated p-worth to decide the factual meaning of your outcomes. On the off chance that the outcomes are genuinely huge, investigate the idea of the distinctions in the three binomial extents.

Question 88

The Sandwich Age How do Americans in the "sandwich age" balance the requests of really focusing on more seasoned and more youthful family members? In a phone survey of Americans matured 45-55 years led by the New York Times,9 the number offering monetary help for their folks is recorded in the following presentation.
