Acknowledge the speed of vehicles along an open stretch of a particular expressway in Texas that isn't energetically journeyed has an around Normal dissemination with a mean of 71 mph and a standard deviation of 3.125 mph.

a) The current posted speed limit is 65 mph. What is the degree of vehicles going over the current posted speed limit?

b) What degree of the vehicles would be going under 50 mph?

c) What degree of the vehicles would be heading off to some place in the scope of 60 and 75 mph?

d) State experts are aware of the road not being seriously managed, and that it can manage a higher speed limit. Regardless, they presently will execute a high cost for speeding over the new speed breaking point to promise some level of as a rule security. Speeds will be checked by radar. Acknowledge a comparable Normal scattering of vehicle speeds continues into the future as already. What should be the new speed limit so much that pretty much 10% of vehicles will speed over the new posted speed limit? Show the sum of your intuition/work in reacting to this.

answer for d

a) Market research has shown that 60% of individuals who are familiar with a particular thing truly buy the thing. A sporadic illustration of 15 individuals were familiar with the thing.

I. Describe the variable of interest for the present circumstance.

ii. What probability scattering do you think best depicts the condition? Why?

iii. Discover the probability that absolutely 9 will buy the thing.

iv. If 80 individuals are familiar with the thing, choose the amount of person who are depended upon to buy the thing.

b) It is understood that an ordinary of 5 trains go through Grand Central Terminal as expected. Find the probability that
