question 47

Multiple Choice

A local retail business wishes to determine if there is a difference in preferred indoor temperature between men and women. A random sample of data is collected, with the following results: What is the decision at the 5% level of significance?

• A) Since the p-value is large at 0.4752, we fail to reject the null hypothesis and conclude that there is no significant difference in the preferred room temperatures between the sexes.
• B) Since the p-value is small at 0.4752, we reject the null hypothesis and conclude that there is a significant difference in the preferred room temperatures between the sexes.
• C) Since the calculated t-value is more than the critical t-value, we reject the null hypothesis and conclude that there is a significant difference in the preferred room temperatures between the sexes.
• D) Since the calculated t-value is more than the critical t-value, we fail to reject the null hypothesis and conclude that there is a significant difference in the preferred room temperatures between the sexes.
• E) There is insufficient information to make a decision.
