Please help me with this hw question.Consider the following situation, and answer each of the followingmultiple choice questions. In your write-up, just list the sub-question letter(A-J) and your answer – no need to restate the question or to justify your answer.Situation: You have 400 data points, which are normallydistributed with a mean of 90 and a standard deviation of 10. All scores areintegers. Then one new data point is added, which is far above the top end ofthe distribution. (Thus, the new data point has the very highest score in thedistribution, by a considerable margin.) A. When the new data point is added, whathappens to the sample size (N)?B. When the new data point is added, whathappens to the mean?C. When the new data point is added, whathappens to the value of the mode?D. When the new data point is added, whathappens to the number of modes in the distribution?E. When the new data point is added, whathappens to the range of the distribution?F. Assuming the standard deviation of the olddistribution was greater than 1, when the new data point is added, what happensto the value of the variance of the new distribution? G. When the new data point is added, whathappens to the value of the skewness of the distribution?H. What happens to the value of the z score of the new mean calculated using the 401 data points, compared to thevalue of the z score of the old mean calculated using the original400 data points?I. What happens to the number of scores thatare greater than 110?J. What happens to the number of scores thatare greater than 170?
