Question

each of 6 students reported the number of movies they saw in the past year. here is what they reported.

8, 17, 12, 16, 17, 18

find the mean number of movies that the students saw.
if necessary, round your answer to the nearest tenth.

movies

Explanation:

Step1: Sum the values

Add up all the numbers: \(8 + 17 + 12 + 16 + 17 + 18\).
Calculating: \(8+17 = 25\), \(25+12 = 37\), \(37+16 = 53\), \(53+17 = 70\), \(70+18 = 88\). So the sum is \(88\).

Step2: Divide by the number of values

There are 6 students, so divide the sum by 6: \(\frac{88}{6}\).
Calculating: \(\frac{88}{6} \approx 14.666\ldots\)

Step3: Round to the nearest tenth

Rounding \(14.666\ldots\) to the nearest tenth gives \(14.7\).

Answer:

\(14.7\)
