For an entire grading period at school, James played video games for 70 minutes a day, and has a GPA of 2.3. For the next grading period his parents said he was not allowed more than 45 minutes of video games each day and his GPA increased to 3.58. Which statement about this situation is true?

A) The number of minutes playing video games varies inversely with GPA with a constant of variation k = 30.4.

B) The number of minutes playing video games varies inversely with GPA with a constant of variation k = 161.

C) The number of minutes playing video games varies directly with GPA with a constant of variation k = 161.

D) The number of minutes playing video games varies directly with GPA with a constant of variation k = 30.4.

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
