Question

Here are the starting salaries, in thousands of dollars, offered to the 20 students who earned degrees in computer science in 2018 at a university copy or use the salary file supplied. 83 78 86 97 70 73 98 75 110 85 84 89 79 96 68 74 69 88 71 70

a. Make a graph to describe the distribution and write a brief description of its important features (center, symmetry or skew, spread, gaps, etc.). You can make a neat and appropriate hand drawing, if you wish.

B. Findthe median salary.

c. Find the mean salary

. d. Find the mode of the salaries.

e. Is the mean about the same as the median or not? What feature of this distribution explains the difference between the mean and the median?

Answer 1

order for given data Answer: 68 69 70 70 71 73 74 75 78 79 83 84 85 86 88 89 96 97 98 110 a HLILLA 1 65-70 71-75 76-80 81-85 86-90 91-95 96-100 lou - 105 106-110 b median middle two value average ob 79+83 2 162 2 > 81 81 : median salary sum of the values mean Number of the valuey +97 +98+110 68+69+70+ 20 - 1643 20 = 82.15 mean salary = 82.15

mode Repeated value in given data = to = 70 mode of the salaries е. mean = 82,15 median = 81 so mean and median are not same and we loole that mean i greter than median so median so the distribution is right skewed and the data contains extreme values
