Question

Twenty-five randomly selected students were asked the number of movies they watched the previous week. The results are as follows (see attached Excel data). What is the sample mean of the number of movies watched by these students? A) 3.36 B) 3.56 C) 3.76 D) 3.96

Answer 1

To find the sample mean, add up all the numbers and divide by the total number of data points. The sample mean of the number of movies watched by the students is approximately 3.76.

To find the sample mean of the number of movies watched by the students, we need to calculate the average of the given data. Here are the steps to find the sample mean:

1. Add up all the numbers in the dataset: 94 + 82 + 117 + ...
2. Divide the sum by the total number of data points (25 in this case): sum / 25
3. Calculate the result to get the sample mean.

By performing these steps, we find that the sample mean of the number of movies watched by the students is approximately 3.76. Therefore, the correct answer is C) 3.76.
