$\left(a\right)$In the article "Material Culture as Memory: Combs and Cremations in Early Medieval Britain" (Early Medieval Europe, Vol. 12, Issue 2, pp. 89-128). H. Williams discussed the frequency of cremation burials found in 17 archaeological sites in eastern England. Here are the data.a. Obtain a normal probability plot of the given data.b. Use part $\left(a\right)$to identify any outliers.c. Use partto assess the normality of the variable under consideration.

a. The above is the normal probability plot for frequency of cremation burials.

b. The outliers are present in the plot at $2484$ .

c. The frequencies of cremation burials are not approximately normally distributed.

See the step by step solution

Part (a) Step 1: Given Information

A normal probability plot of the given data.

First arrange the given data in ascending order and then obtain the normal scores from the table.

Draw the normal probability plot.

Hence, the above is the normal probability plot for frequency of cremation burials.
