The scores are 65, 72, 74, 75, 5,88, 82, 81, 60 , 59, 99, 93, 90, 100, 82, 70, 71, 73, 75, 76.
a.) Is the above data quantitative or qualitative (akacategorical) ?
b.) Find the mean, median, as well as the first and thirdquartiles.
c.) Does the data have any outliers? Prove why.
d.) From comparing the mean to the median, does the data appearto be normal, left skew , or right skew ?(Note: If mean= median or close thisindicates data is normal, if mean < median , the data is skewedleft, if mean > median the data is skewed right).
e.) Now create a histogram and stem/leaf plot for the above. Useclass widths of 10 when creating the histogram. Does the shape ofthe distribution for the stem/leaf plot indicate it is normal ordoes it indicate that it is skewed.
