Question

Please help me, I will give you a shiny medal ^^

A random sample of 100 employees from 5 different companies was randomly selected, and the number who take public transportation to work was recorded. The results are listed below. Perform a homogeneity of proportions test to the claim that the proportion who take public transportation to work is the same in all 5 companies/ Use alpha = 0.01

Answer 1

so I first thought that this would be anova, but it wouldn't work because thats for 3 or more

Answer 2

So would I do: \[\frac{ Row total \times column total }{ total of all values }\]

Answer 3

seems like this is another chi-square goodness of fit test
