Question

A statistician wants to analyze the time spent commuting to work in the morning. To do so she records the time in minutes it takes to get to work each morning for 30 mornings. The data are provided below. Using Excel, calculate the mean, median, and mode of the dataset (round your answers to one decimal place as needed). Provide your answer below:

Answer 1

Explanation:

10,15,17,19,20,21,21,23,26,29.

( rank the number from smallest to largest)

( 10+15+17+19+20+21+21+23+26+29) ÷ 10

= 201 ÷ 10

= 20.1

so the mean is 20.1

The 5th number is 20 and the 6th number is 21

(20+21) ÷2= 20.5

21 appear the most,

so the mode is 21.

mean=20,1

median=20,5

mode= 21
