We collect information from 50 students, 25 men and 25 women, reported the number of hours per week they spent studying statistics. We are going to use the table we made in order to complete parts a and b.

Variable	N	Mean		Minimum	Q1	Median	Q3	Maximum
Men	25	5.78	4.639	1.00	3.00	5	6	18
Women	25	7.68	3.637	3.00	5.00	7	9.50	19

estimate the average time spent on studying statistics (in general - in group of all students you took your sample from) with 90% or 95% confidence
the same but just for men/women
check whether male and female students spend the same number of hours studying statistics (or test that women study more) - test appropriate hypotheses about two means
You may also infer about proportion, like proportion of students studying more than 4 hours weekly - estimate it at some confidence level, verify whether it's more than say 30%.

Definition Definition Middle value of a data set. The median divides a data set into two halves, and it also called the 50th percentile. The median is much less affected by outliers and skewed data than the mean. If the number of elements in a dataset is odd, then the middlemost element of the data arranged in ascending or descending order is the median. If the number of elements in the dataset is even, the average of the two central elements of the arranged data is the median of the set. For example, if a dataset has five items—12, 13, 21, 27, 31—the median is the third item in ascending order, or 21. If a dataset has six items—12, 13, 21, 27, 31, 33—the median is the average of the third (21) and fourth (27) items. It is calculated as follows: (21 + 27) / 2 = 24.
