26.Do men take more time than women to get out of bed in the morning? The 48 men observed averaged 7.2 minutes to get out of bed after the alarm rang. Their standard deviation was 1.1. The 45 women observed averaged 6 minutes and their standard deviation was 2.5 minutes. What can be concluded at the αα = 0.10 level of significance?

For this study, we should use Select an answer t-test for a population mean t-test for the difference between two dependent population means t-test for the difference between two independent population means z-test for the difference between two population proportions z-test for a population proportion
The null and alternative hypotheses would be:

H0:H0: Select an answer p1 μ1 Select an answer = < ≠ > Select an answer p2 μ2 (please enter a decimal)

H1:H1: Select an answer μ1 p1 Select an answer = > < ≠ Select an answer p2 μ2 (Please enter a decimal)

The test statistic ? z t = (please show your answer to 3 decimal places.)
The p-value = (Please show your answer to 4 decimal places.)
The p-value is ? ≤ > αα
Based on this, we should Select an answer reject accept fail to reject the null hypothesis.
Thus, the final conclusion is that ...
Interpret the p-value in the context of the study.
Interpret the level of significance in the context of the study.
- There is a 10% chance that there is a difference in the population mean time for men and women to get out of bed in the morning.
- If the population mean time for men to get out of bed in the morning is the same as the population mean time for women to get out of bed in the morning and if another 48 men and 45 women are observed then there would be a 10% chance that we would end up falsely concluding that the sample mean time for these 48 men and 45 women to get out of bed in the morning differ from each other.
- There is a 10% chance you will take so long to get out of bed in the morning that you will miss the deadline to complete this assignment.

If the sample mean time to get out of bed for the 45 men is the same as the sample mean time to get out of bed for the 45 women and if another 48 men and 45 women are observed then there would be a 0.22% chance of concluding that the mean time to get out of bed for the 48 men is at least 1.2 minutes more than the mean time to get out of bed for the 45 women
There is a 0.22% chance that the mean time to get out of bed for the 48 men is at least 1.2 minutes more than the mean time to get out of bed for the 45 women.

The results are statistically insignificant at αα = 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 αα = 0.10, so there is sufficient evidence to conclude that the mean time to get out of bed in the morning for the 48 men that were observed is more than the mean time for the 45 women that were observed.

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
