Answer:

75


Step-by-step explanation:

The mean [average] of a set of data is "the sum of all the numbers divided by the number of numbers".

<em>How many numbers are in the data set?</em>

<em>15</em>

<u>So we simply add all of them up and divide by sum by 15.</u> Doing so gives us the mean:

Mean = \frac{90+70+63+98+95+32+54+89+84+80+68+71+77+71+83}{15}=\frac{1125}{15}=75

The mean is 75
