The Following Samples Are Observations Taken from the Same Elements

question 108

Multiple Choice

The following samples are observations taken from the same elements at two different times: Perform a test of hypothesis to determine if the difference in the means of the distribution at the first time period is 10 units larger than at the second time period. Use a level of significance equal to 0.10.

• A) Because t = 1.98 > 2.0150, the null hypothesis must be rejected.
• B) Because t = 1.67 > 2.0150, the null hypothesis must be rejected
• C) Because t = 1.02 < 2.0150, the null hypothesis cannot be rejected.
• D) Because t = 0.37 < 2.0150, the null hypothesis cannot be rejected.
