The scatterplot shows the symbiotic blood pressure if people have several different ages equation represents a linear model for this data

Step-by-step explanation:

Here, x represents the age in years and y represents the systolic blood pressure

As per the statement:

The scatter plot shows the systolic blood pressure of people of several different ages.

The equation represents the linear model for this data is:

   [1]

We have to find the systolic blood pressure of someone who is 42 years old.

⇒x = 42 years.

Substitute in [1] we have;

mm Hg

therefore,  the systolic blood pressure of someone who is 42 years old. is, 137 mm Hg

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.
