if you are studying statistics, I find it totally unjustified and unacceptable that you would post this question.
If you have a normal distribution, and it said there is, and the mean is 15, how many would be below this mean and how many would be above this mean ??
Assume x is normally distributed with mean µ= 15 and standard deviation α= 3-. Use the approximate areas beneath the normal curve, as discussed in this section, to answer the following questions. Find P (X ≥15)-
A) 0.50
B) 0.16
C) 0.34
D) 0.84
