12. Suppose a company, with 300,000 employees, decides to give a lie-detector test to all employees to check for theft. Suppose 1 out 300 employees is indeed a thief and that the test has a false positive rate of 4% and a false negative rate of 10%. Assume that by a "negative" test result we mean a test result that suggests that the person is not a thief. What will be probability that an employee who tests positive is in fact a thief?

hello,

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.
