Decide whether the following statements or behaviors are (a) reasonable or plausible, or (b) unreasonable, unlikely, or clearly false. Explain your answer. Not all of these statements have definitive answers, so your explanation is more important than your chosen answer.

a. The variance of a data set is calculated to be -2.8.

b. A certain data set has a bimodal distribution. It has two standard deviation values: 1.5 and 2.8.

c. The standard deviation of a population is a parameter.

d. A certain data set has 26 data points. There is only one deviation score, which is 0.

e. A data set has 26 data points. 13 of them are negative and the other 13 of them are positive numbers. The variance of this data set is 0.

f. The standard deviation of a data set is always 0.

g. Jerry records the jersey numbers of all New York Giants football players. The mean of those jersey numbers is 42 and the standard deviation is 7.2.

h. Eric found the range is 40 and the variance is 200 in his data set.

i. In a negatively skewed distribution, the variance is decreased by the extremely low values.
