  1. The following are 13 observations on burst strength (lb/in2) obtained from a test on a certain type of closure weld. 5900, 6200, 6700, 7200, 7200, 7300, 7300, 7300, 7400, 7400, 7600, 8200, 8300 a. Give the five–number summary of this distribution.
    b. Are there any suspected outliers in the data? If so, which values? (Remember to use the IQR

    formula for determining the existence of outliers.)
    c. From your answer above, create a boxplot for the data and mark/label all points. If there are

    outliers, remember to use a * and the first non-outlier data point instead of the minimum or

    maximum
    d. Based on your boxplot, comment on the symmetry and skew of the dataset. e. What, if anything, can you say about the variation (spread) of the dataset?

A textile mill wants to test the strength of the fiber of a certain batch of cotton. The Pressley Strength Index measures fiber strength in thousands of pounds of pressure required to break the equivalent of one square inch of fiber. The expected strength level for the population of cotton used by the company is a population mean strength of 90 pounds. The sample of 26 pieces of fiber is drawn. The sample has a mean strength of 85.50 pounds...
