Birth weights of newborns are normally distributed with a mean of 10 lbs. and a standard deviation of 4.5 lbs. One selects 32 women randomly and calculates the sample mean birth weight of their children. A. (4 pts.) Determine the sampling distribution of sample mean birth weight. Also, find mean and standard deviation of the sampling distribution. B. (4 pts.) Find the probability that the sample mean of 32 randomly selected babies is greater than 8 lbs.

where is the gragh

step-by-step explanation:

6^2 or 36

step-by-step explanation:

6000n

6×1000n

6×10^3 n

so we need 6n need to be a perfect cube

so n has to be 6^2 so that 6n is 6^3

what i'm saying is if you let n be 6^2 you have 6^3×10^3 or 60^3 which is a perfect cube

a.for lorena 14 hours makes $126   for 16 hours she makes 144
