17 18 20 15 19 10 26 13 17 24 14 26

1.Compute the median. [2pts]

2. interpret the value of the median in a sentence. [3pts]

3. Given that we want to sort data in 4 non overlapping bins, provide lower and upper limits for each of the 4 bins as per the following format.[3pts]

Consider the bin width equal 4. you are given the first bin as shown below.

bin1: [10 13]

bin2: [min max]

bin3: [min max]

bin4: [min max]

4. calculate the frequency of classes, relative frequency and cumulative relative frequency given each bin. [7pts]

bin	frequency	relative frequency	cumulative relative frequency
	[.5pts]	[.5pts]	[1pt]
	[.5pts]	[.5pts]	[1pt]
	[.5pts]	[.5pts]	[1pt]
	[.5pts]	[.5pts]	1

5. interpret the relative frequency values in the table. [4pts]

6. interpret the cumulative relative frequency for bin2. Put your interpretation in a sentence. [4pts]

7. draw the histogram, (use paint, excel or a paper). [3pts]

8. Comment on the shape of the distribution. Justify your answer [4pts]
