The following histogram shows the distribution of 1000 sample observations from a population with a mean of = 4 and a variance of 2 = 8. Suppose a simple random sample of 100 observations is to be selected from the population and the sample average
is calculated.Which of the following statements about the distribution of
is/are FALSE?
A) The distribution of will have a mean of 4.
B) The distribution will be approximately Normal.
C) Because the distribution shown in the histogram above is clearly skewed to the right,the shape of the distribution of will also show skewness to the right.
D) Even though the distribution of the population variable appears to be skewed to the right,the distribution of will be approximately symmetric around = 4.
E) The standard deviation of the distribution of will be 0.283.
