The histogram to the right represents the weights​ (in pounds) of members of a certain​ high-school programmingprogramming team. what is the class​ width? what are the approximate lower and upper class limits of the first​ class? 105 115 125 135 145 155 165 175 0 1 2 3 4 5 6 weight (lbs) frequency a histogram with horizontal axis labeled "weight (pounds)" from 105 to 175 in intervals of 10 and vertical axis labeled "frequency" from 0 to 6 in intervals of 1 contains seven adjacent vertical bars with heights as follows: 105 to 115, 5; 115 to 125, 0; 125 to 135, 1; 135 to 145, 3; 145 to 155, 2; 155 to 165, 5; 165 to 175, 1. what is the class​ width? the class width is 1010. ​(simplify your​ answer.) what are the approximate lower and upper class limits of the first​ class? the approximate lower class limit is 105105. the approximate upper class limit is 115115. ​(simplify your​ answers.) enter your answer in each of the answer boxes.

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.)
