Lines Points A and B are on the horizontal line on either side of the vertical line. Points E and F are on the vertical line on either side of the horizontal line. Another line runs diagonally through the center up to the left and down to the right. Points C and D are on either side of the horizontal line. Measurements for the various angles that are formed are labeled. Angle CA is 1. Angle CE is 2. Angle EB is a right angle and is labeled 3. Angle BD is 4. Angle DF is 5. Angle FA is 6.

Use the figure to answer the question.

B. Image of an angle symbol2 and Image of an angle symbol6
C. Image of an angle symbol3 and Image of an angle symbol4
D. Image of an angle symbol5 and Image of an angle symbol6

In this problem, we explore the effect on the standard deviation of multiplying each data value in a data set by the same constant. consider the data set 14, 6, 8, 15, 15. (a) use the defining formula, the computation formula, or a calculator to compute s. (round your answer to one decimal place.) s = 4.28 (b) multiply each data value by 3 to obtain the new data set 42, 18, 24, 45, 45. compute s. (round your answer to one decimal place.) s = 12.83 (c) compare the results of parts (a) and (b). in general, how does the standard deviation change if each data value is multiplied by a constant c? multiplying each data value by the same constant c results in the standard deviation remaining the same. multiplying each data value by the same constant c results in the standard deviation being |c| times as large. multiplying each data value by the same constant c results in the standard deviation increasing by c units. multiplying each data value by the same constant c results in the standard deviation being |c| times smaller. (d) you recorded the weekly distances you bicycled in miles and computed the standard deviation to be s = 3.8 miles. your friend wants to know the standard deviation in kilometers. do you need to redo all the calculations? yes no given 1 mile ≠1.6 kilometers, what is the standard deviation in kilometers? (enter your answer to two decimal places.)
