b. $7.40
c. $7.00
d. $7.04

ANSWER

C. $ 7.00

EXPLANATION

It was given that four students had the following amounts of money in their pockets: $3.14, $.67, $2.45, and $1.14.

To find the amount of money they have in total, we add all their monies together to get:

$3.14+$0.67+$2.45+$1.14

This will give us a total of $7.00

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
