Three distributions, labeled (a), (b), and (c) are represented below by their histograms. Each distribution is symmetrical and is made of 10 measurements.Without performing any calculations, order their respective standard deviations oa Obr and o°c(a)(b)45 66.10 11 12 13 1412 34 56 7 8 9 10 11 12 13 14Aa(c)1 2 3410 11 12 13 14口>。>。

Solution: σb<σa<σc Reason: Using Histogram we can said that data how much spread. High scatter means high variability. fig b is show less scatters. After fig a and high scatter in fig c. That's why σb<σa<σc this relation happen.

Include appropriate units in the results. How useful a the measures of variation for someone searching for a room? 210 111 162 207 175 158 154 202 The range of the sample data is (Round to one decimal place as needed.) The standard deviation of the sample data is (Round to one decimal place as needed.) The variance of the sample data is (Round to one decimal place as needed.) How useful are the measures of variation for someone searching for a room? O A. The measures of variation are not very useful because the values are nominal data that do not measure or count anything, so the resulting statistics are meaningless. B. The measures of variation are very useful because a person does not want to buy a room where the variation is too high. C. The measures of variation are not very useful because when searching for a room,…
