Question

some students in mr. colemans class recorded the number of pets that they have. pets what is the mean number of pets?

Explanation:

Step1: Count number of students per pet - number

For 0 pets: 3 students.
For 1 pet: 2 students.
For 2 pets: 4 students.
For 3 pets: 3 students.
For 4 pets: 2 students.
For 5 pets: 1 student.
For 6 pets: 1 student.

Step2: Calculate sum of (number of pets * number of students)

$(0\times3)+(1\times2)+(2\times4)+(3\times3)+(4\times2)+(5\times1)+(6\times1)=0 + 2+8 + 9+8+5+6=38$.

Step3: Calculate total number of students

$3 + 2+4+3+2+1+1=16$.

Step4: Calculate the mean

Mean = $\frac{38}{16}=2.375$.

Answer:

$2.375$
