Item 10 find the median, first quartile, third quartile, and interquartile range of the data. 38,55,61,56,46,67,59,75,65,58 !

Median: 58.5; First Quartile: 55; Third Quartile: 65; Interquartile range: 10

Step-by-step explanation: To find the median, you have to have the data set from least to greatest. Then, you cross out the numbers from left to right until you have one number left. To find the first quartile, you find the median of the numbers that are on the left side of the median. You do the same concept for finding the first quartile. To find the third quartile, you have to find the median of the numbers on the right side of the median. To find the interquartile range, you have to subtract the first quartile from the third quartile. In the future, for the mean, you just find the average of the data set. Hope this helps!!

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
