Thank you your assistance is greatly appreciated.

According to the sampling distribution of X we know that: True False If you increasen, the observed sample mean, ã, will always get closer to u = 70. The standard deviation of X is o = 9. The mean of X is u = 70. X always has a normal distribution. O O O O O C
