There is a greater risk of a Type I error with a 0.05 level of significance than with a 0.01 level of significance.
There is a greater risk of a Type I error with a 0.05 level of significance than with a 0.01 level of significance.
This level of significance is more extreme than 0.01. There is a greater risk of a Type I error with a .05 level of significance than with a 0.01 level of significance.
There is a greater risk of a Type I error with a 0.05 level of significance than with a 0.01 level of significance.

Answer to Question 2

ANS: D
The mode is the numerical value or score that occurs with greatest frequency. In this example, the score 12 occurs three times in the data set.
Frequency is how many times a certain score is recorded in the data. The mode is the numerical value or score that occurs with greatest frequency.
The mean is the sum of the scores divided by the number of scores being summed. The mode is the numerical value or score that occurs with greatest frequency.
The median is the score at the exact center of the ungrouped frequency distribution. The mode is the numerical value or score that occurs with greatest frequency.
