Question:
Number of customer in the store during a day follows Normal distribution with mean M and standard deviation ?. Find probability that number of customer during a day will be:
1. Less than x1
P(x
2. Greater than x2
P(x > x2)
3. Between x1 and x2
P(x1
For M, ?, x1, x2 use numbers assigned for you in the table below. convert x1 and x2 to z1, z2 using formula: z = (x - M)/? and use Appendix tables for Normal distribution. Read Lecture material for steps to follow
