Below is the distrubution for number of miles run in a week for a group of 20 runners. Find the mean number of miles run for this group. Use your calculator. Round your answer to the nearest tenth class boundaries frequency
5 - < 10 - 1
10 - < 15 - 2
15 - < 20 - 3
20 - < 25 - 5
25 - < 30 - 4
30 - < 35 - 3
35 - < 40 - 2

Step-by-step explanation:

Added two columns for midpoint and product of frequency and midpoint

Class boundaries >> frequency >> midpoint >> midpoint x frequency

Sum of last column

Mean = sum of last column/ sum of frequencies

Mean

i think its doubled. let me know

step-by-step explanation:

hi there

the slope is 1/3.

this is because from the y-intercept, you go up one, and you go to the right three, to get to the next exact point on the graph. this is known at the “rise over run.”

p.s. (if you need it).your y-intercept is -2, because that is the point on the graph where the line crosses the y-axis.

hope that : )
