Use the body temperatures, in degrees Fahrenheit, listed in the accompanying table. The range of the data is 33F. Use the range rule of thumb to estimate the value of the standard deviation. Compare the result to the actual standard deviation of the data rounded to two decimal places, 0.67F, assuming the goal is to approximate the standard deviation within 02F. a Click the icon to view the table of body temperatures. The estimated standard deviation is I: F. (Round to two decimal plaoes as needed.) Compare the result to the actual standard deviation. The estimated standard deviation is within 02 of the actual standard deviation. Thus, the estimated standard deviation meets the goal.

Compute the grade-point average (GPA). If the dean's list requires a GPA of 3.00 or greater, did this student make the dean's list? The student's GPA is E]. (Type an integer or decimal rounded to two decimal places as needed.) This student did not make the dean's list because their GPA is less than 3.00.

The variation among the male pulse rates is much greater than the variation among the female pulse rates. 0 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 pulse rates. 0 C. 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 the female pulse rates. (9 D. In general, it appears that males have lower pulse rates than females. The variation among the male pulse rates is similar to the variation among the female pulse rates. The blood platelet counts ofa group of women have a bell-shaped distribution with a mean of 250.5 and a standard deviation of 61.2. (All units are 1000 cells/pL.) Using the empirical rule, nd each approximate percentage below. a. What is the approximate percentage of women with platelet counts within 1 standard deviation of the mean, or between 189.3 and 311.7? I). What is the approximate percentage of women with platelet counts between 66.9 and 434.1? a. Approximately .% of women in this group have platelet counts within 1 standard deviation of the mean, or between 189.3 and 311.7. (Type an integer or a decimal. Do not round.) b. Approximately -% of women in this group have platelet counts between 66.9 and 434.1. (Type an integer or a decimal. Do not round.)
