You invite into your home a random individual from a small town. Unfortunately, it's a zombie town and only a few are still normal (including you). You also know that turning into a zombie depends on the degree of exposure to a radioactive substance. The distribution of exposure is normally distributed with a mean of 2700 on radioactive measures, and a SD of 300. A person will turn into a zombie if the radioactivity exposure is at or beyond 2200. What is the probability that the person you just invited might be a zombie -- remember, zombies will eat your brain.

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
