Henry recorded the number of miles he biked each day for a week. his miles were 25, 40, 35, 25, 40, 60, and 75. enter the data into the statistics calculator.

what is the standard deviation of the miles henry biked to the nearest tenth?

17.1

Step-by-step explanation:

1. Find the Mean

(25+40+35+25+40+60+75)/7 = 42.9

2.For each number, subtract the Mean and square the result.

(25-42.86)^2=319

(40-42.86)^2=8.2

(35-42.86)^2=61.8

(25-42.86)^2=319

(40-42.86)^2=8.2

(60-42.86)^2=293.8

(75-42.86)^2=1033

3. Find the Mean of those squared differences.

(319+8.2+61.8+319+8.2+293.8+1033)/7=291.9

4.Take the square root of that and this is what you want.

square root of 291.9 = 17.1

x divided by 8=y
