Question

You want to test the claim made by a college career center that 80% of graduates have full-time employment

within 6 months of graduation. The table below shows data for 300 alumni.

Employed: 210
Unemployed: 90

In the chi-square test, what is the "expected" value for employment?

Select one:

a. 300

b. 210

C. 240

d. 80

Answer 1

240

Explanation:

C. 240

The expected value is calculated by taking the total sample size (300) and multiplying it by the hypothesized proportion of graduates who have full-time employment within 6 months of graduation (80%).

Expected value = 300 x (80/100) = 240
