Question

1-19 one of the ideas that you have explored in previous courses is how to describe a set of data. one of the ways that you may have seen before is finding an average (also called a mean). read the math notes box for this lesson to review what a mean is and how to find it. then find the mean for each set of data below. homework help a) jane’s quiz scores: 82,64,73,91,85 b) the number of cats your teammates have as pets:0,1,3,2 c) the number of minutes pam talked on the phone: 35, 40, 12, 16, 25,10

Explanation:

Part (a)

Step1: Sum the scores

Sum = \( 82 + 64 + 73 + 91 + 85 \)
\( 82+64 = 146 \), \( 146+73 = 219 \), \( 219+91 = 310 \), \( 310+85 = 395 \)

Step2: Divide by number of scores (5)

Mean = \( \frac{395}{5} = 79 \)

Step1: Sum the number of cats

Sum = \( 0 + 1 + 3 + 2 \)
\( 0+1 = 1 \), \( 1+3 = 4 \), \( 4+2 = 6 \)

Step2: Divide by number of teammates (4)

Mean = \( \frac{6}{4} = 1.5 \)

Step1: Sum the minutes

Sum = \( 35 + 40 + 12 + 16 + 25 + 10 \)
\( 35+40 = 75 \), \( 75+12 = 87 \), \( 87+16 = 103 \), \( 103+25 = 128 \), \( 128+10 = 138 \)

Step2: Divide by number of data points (6)

Mean = \( \frac{138}{6} = 23 \)

Answer:

79
