Using the MegaStat Printout Below to Compare the Mean Annual

question 33

Multiple Choice

Using the MegaStat printout below to compare the mean annual incomes for executives with Undergraduate and High School or less, the following statements can be made:

• A) since the 95% confidence interval does not contain the value 0, there is no significant difference in the incomes of these two groups.
• B) since the 95% confidence interval does not contain the value 0, there is a significant difference in the incomes of these two groups.
• C) since the P-value is small, there is a strong chance of these results happening when there is no significant difference in the incomes of these two groups.
• D) since the P-value is small, there is very little chance of these results happening when there is no significant difference in the incomes of these two groups-therefore those executives with an undergraduate degree make more than their counterparts without.
• E) since the 95% confidence interval does not contain the value 0, there is a significant difference in the incomes of these two groups; also, since the P-value is small, there is very little chance of these results happening when there is no significant difference in the incomes of these two groups.
