A student is doing a regression analysis on a data set with an X variable with mean of 5020 parts per million, a minimum of 4300 parts per million and a maximum of 5800 parts per million. They calculate the following prediction intervals for x=5200ppm, x=4500ppm, and x=4100ppm, but mixed up which interval corresponds to which x. • A: (158.39, 164.79)
• B: (164.79, 170.39)
• C: (175.59, 180.59)
With no other information, match prediction interval A, B, and C to the corresponding value of x. How do you know which interval is associated with which X? 6.
One of the intervals in the previous question is invalid: which value of x does it correspond to and why is it invalid?

6.5

the answer i believe is 27 units.

step-by-step explanation:

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.

step-by-step explanation:

the best estimate is 3 because   8 can only go into 24 3 times
