The confidence interval for the mean population of drivers who do not like driving at night is 57.79% - 62.21%.
<h3><u>Confidence interval</u></h3>
To determine what is the 92% confidence interval for the population mean of drivers that do not like driving at night, the following calculation must be performed:
1500 = 100
900 =X
900 x 100 / 1500 = X
60 = X
60 x 0.92 = 55.2
60 x 1.08 = 64.8
Therefore, the confidence interval for the mean population of drivers who do not like driving at night is 57.79% - 62.21%.
