[A, SfS] Chapter 7: Chi-square tests and ANOVA: 7.1: Chi-square Goodness of Fit Test
Chi-square Goodness of Fit Test
An article from 2005 discusses the effects of exposure to beryllium in a cohort of #492# workers at a Beryllium Processing Faculty. These workers were categorized by their disease status ("chronic beryllium disease", "sensitization to beryllium", or "no disease"). The results were as follows:
It is hypothesized that, in the population of all workers involved in processing beryllium, #5\%# are diseased, #10\%# are sensitized, and the remaining #85\%# are not diseased. Are the data in this sample consistent with that distribution?
Carry out a goodness-of-fit test. Report the P-value, using #4# decimal places in your answer.
