A sample of n=16 observations is drawn from a normal population with mean= 1000 and standard deviation= 200.
Find the following:
NOTE: THE BAR IS OVER THE X in each question.
a. P( X > 1,050)
b. P( X < 960)
c. P( X > 1,100)
In each case, we calculate z as z = (x – mean)/(standard deviation/sqrt …
A neat, step-wise solution is provided to calculate z from the sample of a normal population.
