Answer:
d. Yes. All conditions for inference have been met.
Step-by-step explanation:
A study was conducted to investigate the effectiveness of a new drug whether it could significantly reduce pan in people with arthritis.
From a group of 500 people with arthritis 250 were randomly assigned to receive the drug (group 1) and the remaining people were assigned a placebo (group 2).
It is given that the people in the study were selected randomly.
The pooled proportion is given by
Pe = no. of people who reported pain relief in both groups/total number of people
Pe = (225 + 150)/500
Pe = 375/500
Pe = 0.75
Now let us check the condition np ≥ 10
250*0.75
187.5 ≥ 10
Satisfied
Now let us check the condition n(1 - p) ≥ 10
250(1 - 0.75)
250*0.25
62.5 > 10
Satisfied
Therefore, all conditions for inference have been met option d is the correct option.
