As part of a statistics project, a teacher brings a bag of marbles containing 600 white marbles and 300 red marbles. she tells the students the bag contains 900 total marbles, and asks her students to determine how many red marbles are in the bag without counting them. a student randomly draws 150 marbles from the bag. of the 150 marbles, 54 are red. the data collection method can best be described as survey controlled study clinical study census the target population consists of the 300 red marbles in the bag the 900 marbles in the bag the 150 marbles drawn by the student the 54 red marbles drawn by the student none of the above the sample consists of the 54 red marbl

answer: 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.  

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
