Question

these data are the number of on - campus burglaries reported in a given year for nine western pennsylvania universities.
16 10 4 16 9 8 13 5 16
for the above data set, find the mean, median, midrange, and mode. round to one decimal place, if necessary.
part: 0 / 4
part 1 of 4
(a) find the mean.
the mean is □ burglaries.

Explanation:

Step1: Calculate the sum of data

The sum of the data \(16 + 10+4 + 16+9 + 8+13 + 5+16\) is \(97\).

Step2: Calculate the mean

The mean formula is \(\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}\). Here \(n = 9\). So \(\bar{x}=\frac{97}{9}\approx10.8\).

Answer:

\(10.8\)
