Instead of considering a data value to be an outlier if it is "very far away from almost all of the other data values," consider an outlier to be a value that is above Upper Q 3Q3 by an amount greater than 1.5times×IQR or below Upper Q 1Q1 by an amount greater than 1.5times×IQR. Use the data set given below to find (a) the 5-number summary, (b) the interquartile range (IQR), and (c) any outliers. 33 44 55 66 77...

Standard Normal Distribution Activity 1. Roll and record 100 rolls of four, fair six-sided dice. 2. Theoretically, the mean, median, and mode should all be 14. Check to see if this is the case. What is likely to happen to these values if the number of rolls were increased to 200? 300? 1000? 3. Using the calculator, find the standard deviation for the data. 4. Answer the following questions: a. What percentage of the rolls were 12,13, 14,15, or 16?...
