(All units are 1000 cells/L.) 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 69.5 and 446.3? b. What is the approximate percentage of women with platelet counts between 195.1 and 320.7? a. Approximately |% of women in this group have platelet counts within 3 standard deviations of the mean, or between 69.5 and 446.3. (Type an integer or a decimal. Do not round.)

The highest speed measured was 71.9 Mbps. The complete list of 50 data speeds has a mean of x= 17.85 Mbps and a standard deviation of s = 32.46 Mbps a. What is the difference between carrier's highest data speed and the mean of all 50 data speeds? b. How many standard deviations is that [the difference found in part (a)]? c. Convert the carrier's highest data speed to a z score. d. If we consider data speeds that convert to z scores between - 2 and 2 to be neither significantly low nor significantly high, is the carrier's highest data speed significant? a.
