10. (S-AQ 11.45) To estimate the mean height µ of male students on your campus, you will measure an SRS of students. You know from government data that the standard deviation of the heights of young men is about 2.8 inches. You want your sample mean x to estimate p with an error of no more than one-half inch in either direction. What standard deviation (+0.0001) must x have so that 99.7% of all samples give an x within one-half inch of p? (Use the 68-95-99.7 rule)| How large an SRS do you need to reduce the standard deviation of x to the value you found in the previous part? eBook Hint Check Syntax

Assume blood-glucose levels in a population of adult women are approximately normally distributed with mean 90 mg/dL and standard deviation 13 mg/dL. - Suppose the "abnormal range" were defined to be glucose levels outside of 1 standard deviation of the mean (i.e., either at least 1 standard deviation above the mean, or at least 1 standard deviation below mean). What percentage of individuals would be called "abnormal" and need to be retested?
