Answer:

Mean: 44.93

Median:44

Mode: 55

Step-by-step explanation:

MEAN:

Add all the terms then divide the sum with the number of terms:

sum: 629

number of terms: 14

629÷14 = 44.92857143 or 44.93

MEDIAN

Arrange the numbers from lowest to highest. The Median is the Middle term

28, 31, 34, 35, 38, 40, 42, 46, 49, 50, 55, 55, 61, 65

In this case, since there are two middle terms, get their mean

42+46= 88

88÷2= 44

MODE

The Mode is the term with the highest frequency and that will be 55
