Another measure of the spread of a data set is called the range. The find the range, subtract the smallest value from the largest value in a data set.

a. Find the rangĀ  for the data set: 12, 18, 22, 28

b. Although the range is a measure of the spread of a data set, it does not take into account all the values of the data set, since it uses only the largest and smallest values. This is why we need an additional measure like the standard deviation. But the range can be used to estimate the standard deviation in certain cases. Use this formula to estimate the standard deviation for the data set in part a.

Which of the following is NOT a property of the Student's tā€‹ distribution?
Choose the correct answer below.

A) The studentĀ t distribution is different for different sample sizes.
B) The Student t distribution has the same general symmetric bell shape as the standard normalā€‹ distribution, but it reflects the greater variability that is expected with small samples.

D) The standard deviation of the Student t distribution is s equals 1.
