Use the following to answer questions a-g:
Students in an introductory statistics course were asked to count the number of scars on their dominant hand (the one they write with the most). The results are displayed in the provided boxplot.

a. From the boxplot you can identify how many students are in the class (True and False) .
b. Use the boxplot to estimate the median number of scars that students in the class have on their dominant hand.
c. The distribution of the number of scars would be classified as
A) skewed to the left. B) roughly symmetric. C) skewed to the right.
d. Calculate the IQR for the distribution of the number of scars students have.
e. Which answer best describes the following conclusion?
"There are no students with 7 scars on their dominant hand."
A) True B) False C) Cannot be determined
f. Which answer best describes the following conclusion?
"There are no students with 2 scars on their dominant hand."
A) True B) False C) Cannot be determined

45

step-by-step explanation:

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.

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
