Math unit nine statistics lesson five summarizing data quick check five questions I need help please summarized the following data set by calculating the mean if necessary round to the nearest whole number the numbers are five, five, five, 10, 15, 20, 30, 40, 100, and 120 would the answer be 35 or five or 18 or 115?

Answer 1

To calculate the mean of the data set, you need to add all the numbers together and then divide by the total number of values.

5 + 5 + 5 + 10 + 15 + 20 + 30 + 40 + 100 + 120 = 350

Dividing by the total number of values (10), the mean is 350 / 10 = 35

Therefore, the correct answer is 35.
