Answer:
The confidence interval is (0.81, 0.87).
Step-by-step explanation:
There's 90% confidence that population proportion is within the interval obtained from the following formula:
Knowing that the sample size, we obtain the proportion of people from the sample who leave one space after a period as
.
We then look for the critical value:
Now we can replace in the formula to obtain the confidence interval:
Therefore we can say that there's 90% probability that the population proportion of people who leave one space after a period lies between the values (0.8137; 0.8663).
