Answer:
The minimum sample size to have this margin of error is n = 897.
Step-by-step explanation:
We have to estimate a parameter with a confidence interval. The confidence level is 95% and the margin of error is 0.5 days.
The population standard deviation is 7.64 days.
The critical value of z for a 95% confidence interval is z=1.96.
We have to calculate the minimum sample size.
To do that, we use the margin of error formula in function of n:
The minimum sample size to have this margin of error is n = 897.
