mean (μ) = 7 and standard deviation (σ) = 1.5.
The z score is used in statistic used to measure the number of standard deviation by which the raw score is above or below the mean value. It is given by:

To find the Probability that x < 8.8, we first find the z score using:

From the z tables, P(x < 8.8) = P(z < 1.2) = 0.8849 = 88.49%

Speed of Morris is 47.95 mph
Step-by-step explanation:
- Step 1: Convert 3 feet per second to miles per hour.
⇒ 3 ft/s = 3/1.467 mph (∵ 1 mph = 1.467 ft/s)
= 2.05 mph
- Step 2: Find the speed of Morris.
Speed of Morris = 50 mph - 2.05 mph = 47.95 mph
