Question

The number of hours per week that the television is turned on is determined for each family in a sample. The mean of the data is 39 hours and the median is 35.2 hoursTwenty-four of the families in the sample turned on the television for 24 hours or less for the weekThe percentile of the data is 24 hours Step 2 of 5Approximately how many families are in the sample? Round your answer to the nearest integer

Answer 1

To determine the approximate number of families in the sample, you can use the given information about the percentile.

In this case, you know that 24 families turned on the television for 24 hours or less for the week. This means that the 24-hour mark corresponds to the 0th percentile of the data.

Since the mean and median are also given, you can assume that the data is normally distributed. In a normally distributed dataset, the 0th percentile corresponds to the minimum value.

Therefore, you can assume that the minimum value in the dataset is 24 hours. Since this represents the 0th percentile, it implies that there are 24 families in the sample with a value of 24 hours.

Rounding to the nearest integer, the approximate number of families in the sample is 24.
