Pine trees and juniper trees are common to the San Bernardino
mountains. Pine trees have a mean height of 52 meters with a
standard deviation of 3 meters. Juniper trees have a mean
height of 22 meters with a standard deviation of 5 meters.
(a) At the base of a trail, there is a 48-meter-tall pine tree and a
33-meter-tall juniper tree. Calculate the Z-score for each of
these trees.
If necessary, round your answers to the nearest 2 decimal
places. Write both answers in the text box below.

Each of the following data sets has a mean of x = 10. (i) 8 9 10 11 12 (ii) 7 9 10 11 13 (iii) 7 8 10 12 13 (a) without doing any computations, order the data sets according to increasing value of standard deviations. (i), (iii), (ii) (ii), (i), (iii) (iii), (i), (ii) (iii), (ii), (i) (i), (ii), (iii) (ii), (iii), (i) (b) why do you expect the difference in standard deviations between data sets (i) and (ii) to be greater than the difference in standard deviations between data sets (ii) and (iii)? hint: consider how much the data in the respective sets differ from the mean. the data change between data sets (i) and (ii) increased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). the data change between data sets (ii) and (iii) increased the squared difference îł(x - x)2 by more than data sets (i) and (ii). the data change between data sets (i) and (ii) decreased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). none of the above
