Question

Suppose a normally distributed set of data has a mean of 193 and a standard deviation of 13. Use the 68-95-99.7 Rule to determine the percent of scores in the data set expected to be below a score of 219. Give your answer as a percent and includeas many decimal places as the 68-95-99.7 rule dictates. (For example, enter 99.7 instead of 0.997.)

Answer #1

Suppose a normally distributed set of data with 2100
observations has a mean of 130 and a standard deviation of 19. Use
the 68-95-99.7 Rule to determine the number of observations in the
data set expected to be above a value of 111. Round your answer to
the nearest whole value.

Suppose a normally distributed set of data with 8000
observations has a mean of 167 and a standard deviation of 11. Use
the 68-95-99.7 Rule to determine the number of observations in the
data set expected to be above a value of 145. Round your answer to
the nearest whole value.
