Answer 2

Answer:

Mean of all prime numbers between 50 and 80 = 66.143

Step-by-step explanation:

Mean of a data set = (sum of data)/(total number of data)

The prime numbers between 50 and 80

53, 59, 61, 67, 71, 73 and 79

There are 7 numbers

To find the sum of numbers

Sum= (53 + 59 + 61 + 67 + 71 + 73 +79) = 463

To find the mean

Mean = Sum of data/total number of data

Sum of data = 463

total number of data = 7

Mean = 463/7 = 66.143
