The following data values represent a population. What is the variance of the values? 7, 5, 11, 1, 11

MaRussiya [10]

The mean is 35/5=7

The variance is the average of the sum of squared differences of each element from the mean:

v=((7-7)^2+(5-7)^2+(11-7)^2+(1-7)^2+(11-7)^2)/5

v=(0+4+16+36+16)/5

v=14.4

A histogram is used to show the frequency of data, where the length of the bar represents the frequency.

50 students drank the recommended amount of water.

The recommended amount is given as:

$Amount \ge 48$

See attachment for histogram.

From the histogram, we have the following observations

The lengths of all bars of the histogram are less than 48, except one.

The length of the bar above 48 is 50.

This means that: 50 students drank the recommended amount of water.

Hence, the number of students is 50
