Consider a random variable X that is normally distributed. Complete parts (a) through (d) below. (This is a reading assessment question. Be certain of your answer because you only get one attempt on this question.)

If a random variable X is normally distributed, what will be the shape of the distribution of the sample mean?

A. Normal
B. Skewed left
C. Skewed right
D. Cannot be determined

If a random variable X is normally distributed, what will be the shape of the distribution of the sample mean?

So long mean is a linear combination of normal independent variates, then the shape of distribution of the sample mean is normal.

Step-by-step explanation:

So long mean is a linear combination of normal independent variates, then the shape of distribution of the sample mean is normal.

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
