Homework Help: Math

Posted by Gia on Friday, June 1, 2012 at 3:35am.

"Last year, the personal best high jumps of track athletes in a nearby state were normally distributed with a mean of 229 cm and a standard deviation of 19 cm. What is the probability that a randomly selected high jumper has a person best between 229 and 248 cm?"

I think the answer is 16%. Could someone check this for me?

"According to a poll conducted in a company, 47% of the employees regularly use the internet while at work. You conduct a similar survey at your mother's office where there are 250 respondents. What is the probability you find between 102 and 117.5 employees who use the internet while at work?"

I think the answer for this one is 47.5%, so could someone also check this one?
