The dot plots below show the ages of students belonging to two groups of music classes: a dot plot shows two divisions labeled group a and group b. the horizontal axis is labeled as age of music students in years. group a shows 5 dots at 6, 5 dots at 8, 3 dots at 9, 7 dots at 11, and 5 dots at 13. group b shows 2 dots at 6, 4 dots at 10, 4 dots at 13, 3 dots at 15, 5 dots at 16, 4 dots at 19, and 3 dots at 21. based on visual inspection, which group most likely has a lower mean age of music students? explain your answer using two or three sentences. make sure to use facts to support your answer.

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: its c because when it has a magnet next to it it will move away from the mixture. hope this
