27. Below are the jersey numbers of 11 players randomly selected from a football team. Find the range, variance, and standard deviation for the given sample data. What do the results tell us'? 19 46 23 99 60 72664 94 31 86% Range : (Round to one decimal place as needed) Sample standard deviation 2 (Round to one decimal place as needed ) Sample yanance 2 (Round to one decimal place as needed) What do the results tell us'? O A. Jersey numbers on a football team do not vary as much as expected. 0 B. The sample standard devratlon is too large in comparison to the range. 0 C. Jersey numbers on a football team vary much more than expected. 0 D. Jersey numbers are nominal data that are just replacements for names, so the resulting statistics are meaningless. 28. A sample of blood pressure measurements is taken for a group of adults, and those values (mm Hg) are listed below. The values are matched so that 10 subjects each have a systolic and diastolic measurement. Find the coefficient of variation for each of the two samples; then compare the variation. Systolic 118 128 158 95 158 120 114 138 124 122 0 Diastolic 81 78 74 50 88 89 60 64 74 82 The coefficient of variation for the systolic measurements is % (Type an integer or decimal rounded to one decimal place as needed.) The coefficient of variation for the diastolic measurements is yo. (Type an integer or decimal rounded to one decimal place as needed.) Compare the variation. The coefficients of variation for each data set are (1) Therefore, the systolic measurements vary (2) the diastolic measurements. (1) O more than 5 percentage points apart. (2) O significantly less than O within 5 percentage points of each other. O significantly more than O about the same as29. The blood platelet counts of a group of women have a bell-shaped distribution with a mean of 257.5 and a standard deviation of 61.2. (All units are 1000 cells/uL.) Using the empirical rule, find each approximate percentage below. a. What is the approximate percentage of women with platelet counts within 3 standard deviations of the mean, or between 73.9 and 441.1? b. What is the approximate percentage of women with platelet counts between 135.1 and 379.9? a. Approximately % of women in this group have platelet counts within 3 standard deviations of the mean, or between 73.9 and 441.1. (Type an integer or a decimal. Do not round.) b. Approximately of women in this group have platelet counts between 135.1 and 379.9. (Type an integer or a decimal. Do not round.)33. Use the same scales to construct boxplots for the pulse rates of males and females from the accompanying data sets. Use the boxplots to compare the two data sets. 1 Click the icon to view the data sets. Determine the boxplot for the men's pulse rate data.

In general, it appears that males have higher pulse rates than females. The variation among the male pulse rates is much greater than the variation among th J B. In general, it appears that males have higher pulse rates than females. The variation among the male pulse rates is similar to the variation among the female O C. In general, it appears that males have lower pulse rates than females. The variation among the male pulse rates is much greater than the variation among the https:/ditemprod.pearsoncig.com/api/v1/print/highered 1/2 6/29/22, 3:53 PM Go .
