question 56

Multiple Choice

i. We use the pooled estimate of the proportion in testing the difference between two population
Proportions when the samples are not chosen independently.
ii. The pooled estimate of the proportion is found by dividing the total number of samples by the
Total number of successes.
iii. A committee studying employer-employee relations proposed that each employee would rate his
Or her immediate supervisor and in turn the supervisor would rate each employee. To find reactions
Regarding the proposal, 120 office personnel and 160 plant personnel were selected at random.

Computed z = 1.48. At the 0.05 level, it was concluded that there is sufficient evidence to support
The belief that the proportion of office personnel in favour of the proposal is greater than that of the
Plant personnel.
