The box plots below show student grades on the most recent exam compared to overall grades in the class: Which of the following best describes the information about the medians? (1 point)

a
The exam outlier at 60 makes the IQR narrower and the median higher.

b
The class data is more evenly spread, which pulls its median down.

c
The class median is lower than the exam median.

d
The class Q3 is higher than the exam Q3.

I know alot of people have gotten this wrong and the answer is not The class Q3 is higher than the exam Q3. If you can help me you will also be helping others who need the answer to this question so this will greatly be appreciated.

a: 1/6, j: 1/4

step-by-step explanation: you are welcome

the anwser is d) 75°

step-by-step explanation:

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
