The blood platelet counts of a group of women have a bell-shaped distribution with a mean of 259.1 and a standard deviation of 67.9. (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 55.4 and 462.8?b. What is the approximate percentage of women with platelet counts between 191.2 and 327.0?a. Approximately % of women in this group have platelet counts within 3 standard deviations of the mean, or between 55.4 and 462.8.(Type an integer or a decimal. Do not round.)

Given : Mean , u = 259.1 standard deviation, σ = 67.9

Total plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual.

Assume that ? = 7.20 ml/kg for the distribution of blood plasma.

Historically, Olympic officials have reported testosterone levels in general should be u = 538 ng/dL, with o = 189, with x being normally distributed. Summer Olympic sprinters (n = 8) from the U.S. were tested for testosterone levels the morning after the opening ceremonies. Their sample mean was ng/dL. Do these data indicate that the sprinters had an overall average testosterone level greater than 538? Use a = .05. State a, H,, H1, p-value, rejection, or non-rejection, and be certain to interpret your results.
Use the Empirical Rule. The mean speed of a sample of vehicles along a stretch of highway is 68 miles per hour, with a standard deviation of 3 miles per hour. Estimate the percent of vehicles whose speeds are between 65 miles per hour and 71 miles per hour. (Assume the data set has a bell-shaped distribution.) Approximately nothing% of vehicles travel between 65 miles per hour and 71 miles per hour.
