Percentage of Scalp Covered by Hair The normal curve above describes the percentage of scalp coverage of men of age 50. The mean value of the data is 32% scalp coverage and the standard deviation is 10%. a. In which range of values, centered at the mean, do 68% of the data fall? 95% of the data?
b. 7% of a 50-year-old professor’s scalp is covered by hair. What is the z-score of this professor’s scalp coverage?
c.
How many standard deviations away from the mean is this professor’s scalp coverage?
d. A 50-year-old female colleague of the above professor has 60% of her scalp covered by hair. 50 year-old female scalp coverage is described by the normal distribution N(80,10). What is the z-score of the female professor’s scalp coverage?
