Drew tries to predict which restaurant will have at least amount of business during Christmas season. There are three restaurant in the city. Two are on the outskirts of the city and one is in the city. He learned that two hotels situated on the outskirts are fully booked because one has a huge indoor pool. From this information he inferred that the restaurant in the city will have the least amount of business during the Christmas season. What would have been an improvement in Drew's experiment? A. ask people at the restaurant if they like fast food.
B. survey all people to see which December holiday they celebrate.
C. look at the past holiday performance of the restaurant.

A

Step-by-step explanation:

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.
