Please watch the following two videos and then answer the questions below.  (You may want to answer in word and then insert the screenshots where appropriate.) For number 5. please show me that you can get the result with the TI-84 and also in JMP by attaching screenshots of each.  For number 6b) please attach a screenshot of your calculator showing how you obtaining the result. 

1.     P( z < 1.2)

2.    P(z > 1.2)

3.    P( -1.3 < z < 0.8 )

4.    P( x < 12 ) mean = 11,  standard deviation = 2

5.    P( 8 < x < 12 ) mean = 11,  standard deviation = 2

6.    Suppose that fuel efficiency (miles per gallon, mpg) for a particular car model under specified conditions is normally distributed with a mean value of 30.0 mpg and a standard deviation of 1.2 mpg.

      a) What is the probability that the fuel efficiency for a randomly selected car of this model is between 29 and 31 mpg?

      b) Find a number x∗x∗such that 95% of all cars of this model have efficiencies exceeding x∗x∗(i.e., P(x>x∗)=0.95P(x>x∗)=0.95)
