Answer:
0.245
Step-by-step explanation:
In order to find find the probability that the mean of the groups age is between 90 and 100 months, we have to find z for each value
Z = (x – mean)/standard deviation
Le x be the average age of a vehicle
Z1 = (90 – 96)/16 = -0.375
Z2 = (100 – 96)/16 = 0.25
Then we use the z table to find the area under the curve.
Area for Z1 = 0.354
Area for Z2 = 0.599
The probability that the mean of the groups age is between 90 and 100 months can be found as follows:
0.599 – 0.354 = 0.245
Angle HDF is 135 degrees as well. Alternate exterior angles are congruent. :)
