thursday	460
friday	710
saturday	670

what is the mean, median, and range, respectively, of the amount of calories burned over a week?
o 4020, 460, and 370
o 574.3, 460, and 150
o 574.3, 460, and 370
o 574.3, 590, and 370

Explanation:

Step1: Calculate the mean

Mean = $\frac{700 + 340+590 + 460+710+670+550}{7}=\frac{4020}{7}\approx574.3$

Step2: Find the median

Arrange data in ascending order: 340, 460, 550, 590, 670, 700, 710. Middle - value (n = 7, odd number) is 590.

Step3: Calculate the range

Range = Maximum value - Minimum value = 710 - 340 = 370

Answer:

C. 574.3, 590, and 370
