Example 7.8 from Statistics, 7.3 Using the Central Limit Theorem
(part 1)
a. Find P( < 2). Draw the graph.
Work it out on paper first. Then open the solution one step at a time, and stop as soon as you can finish on your own.
Solution
a. P( < 2) = 0
The probability that the mean stress score is less than 2 is about zero.
Figure 7.4normalcdf= 0Reminder
The smallest stress score is one.
How did it go?
