While at summer camp, mike asked a random camper from each of the 12 cabins how many siblings he or she had. the results below display the responses. 3, 2, 0, 1, 0, 2, 3, 4, 1, 2, 2, 1 if there are 48 campers altogether, use mike’s data to infer the mean of the population. what is the mean number of siblings for the population rounded to the nearest unit?

The mean number of siblings for the population rounded to the nearest unit is:

                                     2

We know that a mean of a data is the average of the data points i.e. it is calculated as the ratio of the sum of all the data to the number of data points.

Here we have a total of 12 data points such that the value is given by:

3, 2, 0, 1, 0, 2, 3, 4, 1, 2, 2, 1

Now, the mean of this data is calculated as:

Hence, round to the nearest unit the mean of the data is: 2

hi,

3. 12.15, you are correct.

4.2.01, your first digit is correct,

hope this !

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing
