Question 903707
P(x < value) = P(x &#8804; value).
TI syntax is normalcdf(smaller, larger, µ, &#963;).
Note: The -999 is used as the smaller value to be at least 5 standard deviations from the mean.

1- normalcdf(-999,61,56,3.2)
b)what is the probability that a randomly selected hybrid gets more than 50 miles per gallon or less? 
nomalcdf(-999, 50,56,3.2)
c) what is the probability that a randomly selected hybrid gets between 58 and 61 miles per gallon? 
normalcdf(58,61, 56,3.2)
d) what is the probability that a randomly selected hybrid gets less than 45 miles per gallon? 
normal(-999,44,56,3.2)
