Answer questions (a-d) for the following three data sets.
a= {3,5,7,9,11,12,12}
b= {1,2,2,5,5,9,13}
c= { 2,5,8,9,12,13,17}

a) find the mean of each data set
b) find the standard deviation of each data set
c) identify the data set with the largest and smallest standard deviation
d) explain what the standard deviations say about the data sets

Step-by-step explanation:

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
