In independent random samples of 10 men and 10 women, the numbers of minutes spent working out are given by the back-to-back stemplots below: Row 1 contents are Men; bar; blank; bar; Women. Row 2 contents are 1; bar; 1; bar; 3, 5. Row 3 contents are blank; bar; 2; bar; 4. Row 4 contents are blank; bar; 3; bar; 2, 3, 6,7. Row 5 contents are blank; bar; 4; bar; blank. Row 6 contents are 6, 7; bar; 5; bar; 0, 3. Row 7 contents are 8; bar; 6; bar; blank. Row 8 contents are 5; bar; 7; bar; blank. Row 9 contents are 6, 1; bar; 8; bar; blank. Row 10 contents are 7, 5, 4; bar; 9; bar; 5.

Part A: Describe the shape of each data set. (3 points)

Part B: Coraline analyzed the data and stated that the better measure of center for the women is the median. Is Coraline correct? Explain your reasoning. (3 points)

Part C: Coraline decided there are no outliers in the women's data set. Is she correct? Justify your answer mathematically. (4 points) (10 points)

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
