The data were collected from a statistics class. The column head gives the variable, and each of the rows represents a student in the class. Find the frequency, proportion, and percentage of women. Click the icon to view the data table. X Stats class data The frequency of women in the class is (Type an integer or a decimal.) Male Age Eye Shoe Height | Weight|Number College Units Color Size (inches) (pounds) of Siblings This Term Handedness The proportion of women in the class is 0 29 Hazel 7 62 170 2 5 Right (Type an integer or a fraction.) 0 20 Blue 12 67 135 Right 1 20 Brown 11 71 155 ONA 12 Right The percentage of women in the class is % 1 32 Hazel 7.5 73 205 11 Right (Round to one decimal place as needed.) 1 19 Hazel 9.5 60 125 6 7 Right 1 20 Hazel 9.5 72 135 9 Right 1 30 Blue 7.5 62 150 2 15 Right 1 24 Brown 10 60 185 7 12 Right 1 23 Hazel 7 73 120 11 Right 1 20 Brown 8.5 73 190 NO - 8 Left 0 20 Hazel 11.5 62 145 13 Right 4 Print DoneThe accompanying dotplot is for resting pulse rates of 125 people. Many sources say the resting pulse rate should not be more than 100. a. How many of the 125 people had resting pulse rates of more than 100? b. What percentage of people had resting pulse rates of more than 100? Ii Click the icon to View the dotplol. Resting Pulse Rates a, There are people who had resting pulse rates of more than 100 (Type a whole number) b, Out of 125 people' % had resting pulse rates of more than 100, (Type an integer or decimal rounded to one decimal place as needed.) 70 80 90 100 Pulse rate (beats per minute] Done The accompanying histogram is for pulse rates for 125 people. From the accompanying histogram, approximately what is the typical pulse rate in this sample? Click the icon to view the histogram. X Pulse Rates The typical pulse rate in this sample is approximately beats per minute. 30- 25- 20- Frequency 15- 10- 40 50 60 70 80 90 100 110 120 130 Pulse rate (beats per minute) Print Done Activate\fThe histograms show triglyceride levels for 102 men and 100 women. Triglycerides are a form of fat found in blood. Complete parts (a) and (b) below. Click the icon to view the histograms. a. Compare the distribution of triglyceride levels for men and women. (Be sure to compare the shapes, the centers, and the spreads.) The distribution for women is The distribution for men is Compare the centers of the distributions. Choose the correct answer below. O A. The two distributions have similar typical values. O B. The distribution for women has a significantly greater typical value than the distribution for men. O C. The distribution for men has a significantly greater typical value than the distribution for women. O D. Neither distribution has a clearly defined typical value. Which group has more variation in its triglyceride levels? O A. Women, because their distribution has a larger spread than men O B. Men, because their distribution has a larger spread than women O C. Women, because the mode(s) of their distribution has(have) a higher frequency than the men's O D. Men, because the mode(s) of their distribution has(have) a higher frequency than the women's b. Triglyceride levels under 150 are good; levels above 500 are very high and may be a health concern. Which group seems to have better triglyceride levels? Explain. O A. The women's distribution has a greater typical value, so the men's levels are somewhat better. O B. The men's distribution has a greater typical value, so the women's levels are somewhat better. O C. The women's distribution is more spread out and has a greater percentage of values that are considered high, so the men's levels are somewhat better
