To determine what sizes and how many of each size to manufacture, they collected a random sample of 50 women and measured their shoe sizes. Here are the results: 5.5 6.5 5.5 4.5 5 6. 5.5 5.5 6.5 6 5.5 4.5 5 6. 5.5 6 6. 5 6.5 7 6. 6.5 5 6.5 5.5 5.5 7 6.5 7.5 5.5 6 5.5 6.5 7.5 4.5 4 5.5 6 5 5 6.5 5 4 6. 5.5 Calculate the mean and standard deviation of the sizes and interpret the results in terms of what relative quantities of which sizes the factory should make. Then find the five-number summary and decide which set of information gives you more assistance in making a decision for the shoe factory.

Corvallis, OR: Forest Science Data Bank, 2005. (a) Obtain a point estimate for the mean and standard deviation diameter of a Douglas fir tree in the western Washington Cascades. (b) Because the sample size is small, we must verify that the data come from a population that is normally distributed and that the data do not contain any outliers. The figures show the normal probability plot and boxplot. The correlation between the tree diameters and expected z-scores is 0.982. Use Option 1 or Option 2 to determine if the…
