Expert Solution
Step 1

Given that

Level of significance = 5%

Sample of 66 males 50 are working.

Sample of 81 females 49 are working.

Step 2

To prove that the percentage of male students working is greater than the female working students.

For this, we use two proportion z test.

Set up the hypothesis:

Null hypothesis H,: Pmk = Pg emale ale Alternative hypothesis H : P P. female male
Step 3

The test statistic is

Pmok - Pfemae female where, 50 Pmate = =0.7575 66 49 = 0.6049 81 Pjemole
Step 4

Where

50 + 49 P. 66 + 81 99 147 P. = 0.67 1- p. = 0.33 0.67(0.33) 0.67(0.33) 66 81 0.2211 0.2211 66 81 = V0.00335+0.00273 /0.00608 = 0.0779 maie
