There are 16 total students who bought their lunch.

(a) Make sure you understand this ratio. Fill in the blanks below:
Kids in
For every
kids in the cafeteria kids bought their lunch. Cafeteria

(b) Let t represent the total number of students
in the cafeteria. Set up a proportion to find
the value of t and solve it.

(c) How many students did not buy their
lunch (brought it)?

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:

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =
