For the followingproblem, use the68-95-99.7 Rule to approximate the probability rather than using technology to find the values more precisely.

Although controversial and the subject of some recent lawsuits, some human resource departments administer standard IQ tests to all employees. One IQtest's scores are well modeled by a Normal model with mean 100 and standard deviation 19. If the applicant pool is well modeled by thisdistribution, a randomly selected applicant would have what probability of scoring in the followingregions?

a) 81 or below

b) Above 100

c) Between 43 and 157

d) Above

Please answer all parts, thank you!
