A recent flight from College Station to Dallas had 30 passengers on it. 12 passengers drank soda during the flight. 20 passengers drank water. 6 did not want a drink on the flight. (The flight only had soda and water to offer to passengers on this particular flight.) Questions:
A) How many passengers only drank water?
B) How many drank only ONE of these two things?

see below

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.

step-by-step explanation:

d. you cannot tell because there are no values shown.
