The box plot shows the algebra scores of students in class A and class B. The median score of class A is _.

The interquartile range of class B is _.

The difference of the medians of class A and class B is
the interquartile range of either data set.

The difference of the medians of class A and class B is between  the interquartile range of either data set.

Step-by-step explanation:

Given

The attached box plots

To answer this, see attached image for how to read a box plot

With reference to the attached image of how to read the box plot;

Solving (a): The median of class A

Solving (b): IQR of class B

IQR is calculated as:

From the box plot of class B, we have:

So, we have:

Solving (c):

IQR of class A is calculated as:

From the box plot of class A, we have:

So, we have:

The difference (d) between the medians is:

From to , we have: 8, 9, 10

i.e. IQR(B), d, IQR(A)

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560

4+4+2x

or

2x+8
