{20, 68, 70, 70, 71, 72, 75, 76}
a. What is the mean?
b. What is the median?
c. What is the mode?

Mean: 65.25

Median: 70.5

Mode: 70

Step-by-step explanation:

Mean is the sum of the set of numbers divided by the number of numbers in the set.

20+68+70+70+71+72+75+76=522

522/8=65.25

The median is the number that is in the middle of the set when put in numerical order.

Since there is an even amount of numbers, the two middle numbers are 70 and 71, so you would take the mean of these two numbers to find the median.

70+71=141

141/2=70.5

The mode is the number that occurs most frequently in the set.

70 appears more times than any other number, therefore it is the mode.

mean:65.25

median:70.5

mode:70

Step-by-step explanation:

mean: add up all numbers which will give u 522 then u divide the amount of numbers which is 8 then you'll get 65.25.

median: u would find the middle number by putting all numbers into ascending order and work into the middle by crossing off numbers at each end. which will leave u with 2 numbers 70,71 so u add them and get 141 then divide by 2 which is 70.5.

Mode: find the most common number which is 70

hey i’m new i won’t be answering any questions now bye peeps see you next time
