2. a pet food company wants to know the number of pets owned by adults ages 21 to 70. the frequency table shows the data from a simple random sample of the targeted population. total pets owned 1 2 3 4 5 6 7 number of adults 248 567 1402 728 419 456 203 what is the estimated mean for the population? explain your answer and show your work.

3.6669

Step-by-step explanation:

Given is a frequency distribution and we are expected to find the mean of the distribution.

Let X be the no of total pets owned and f be the number of adults owning those pets.

                                                          Total

x   1    2    3           4          5                   6                 7    

F2485671402728         419                 456                203     4023

x*f2481134420629122095        2736         1421     14752

Mean        3.666915237

Thus we find the total of all frequencies and then sum of product of x*f.

Mean = sum of f*x/sum of x

Here mean= 3.6669

step-by-step explanation:

just count the values of x & y of the vertex of the graph and see how many units in the x and y direction will get you from the f(x) graph to the f(x) graph

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
