**Question description**

I am stuck on one of my statistics homework questions. This is the only question I am unsure of. Can anyone help me? The statistics problem is:

The results of a random sample of the number of pets per household in a region are shown in the histogram. Estimate the sample mean and the sample standard deviation of the data set.

The number of 0 pets was 5 households, the number of 1 pet was 10 households, the number of 2 pets was 11 households,the number of 3 pets was 9 households, and the number of 4 pets was 11 households.

My answer has to be rounded to one decimal place. Can anyone help me?
