Answer 1

First we need to find the mean and SD of data sets. Following is the output of descriptive statistics:

Descriptive statistics
	Female Hours of Sleep:	Male Hours of Sleep:
count	17	18
mean	6.824	7.556
sample standard deviation	1.2367	1.5038
sample variance	1.53	2.26
minimum	4	4
maximum	8	10
range	4	6

---------------------------------------------

Conclusion: There is no evidence to conclude that the mean hours of sleep for males and the mean for females are significantly different.
