Do men take more time than women to get out of bed in the morning? A simple random sample of 51 men averaged 4.8 minutes to get out of bed after the alarm rang with a standard deviation of 2.6. A simple random sample of 56 women averaged 4 minutes with a standard deviation of 2.4 minutes. Let1be the average time for all men to get out of bed and2be the average time for all women to get out of bed. What can be concluded at the= 0.10 level of significance?

7.Thus, the final conclusion is that ...

• The results are statistically insignificant at= 0.10, so there is statistically significant evidence to conclude that the population mean time for men to get out of bed in the morning is equal to the population mean time for women to get out of bed in the morning.
• The results are statistically significant at= 0.10, so there is sufficient evidence to conclude that the population mean time for men to get out of bed in the morning is more than the population mean time for women to get out of bed in the morning.
• The results are statistically insignificant at= 0.10, so there is insufficient evidence to conclude that the population mean time for men to get out of bed in the morning is more than the population mean time for women to get out of bed in the morning.
• The results are statistically significant at= 0.10, so there is sufficient evidence to conclude that the mean time to get out of bed in the morning for the 51 men that were observed is more than the mean time for the 56 women that were observed.
