According to the study of weights of males from years 2006 to 2016, the average weight for men aged 18-55 years is 185 pounds with a standard deviation of 30 pounds. Assuming that weights of men aged 18-55 are normally distributed, using the Empirical Rule, about 95% of male weight fall between what two values?

According to the study of weights of males from years 2006 to 2016, the average weight for men aged 18-55 years is 185 pounds with a standard deviation of 30 pounds. Assuming that weights of men aged 18-55 are normally distributed, using the Empirical Rule, about 99.7% of male weight fall between what two values?

How strong is the linear relationship between the age of a driver and the distance the driver can see?  A research firm (Last Resource, Inc., Bellefonte, PA) collected data on a sample of n = 30 drivers. Use the two variables to conclude it there is a linear relationship between a person’s distance they can read a sign and a person’s age. Use Distance (y) as a function of Age (x). Here is the Data Set on StatCrunch.
