Question

A small chain hardware store operates in four different states (Florida, Georgia, Alabama, and Mississippi). The store owner would like to know if 4 different types of items purchased (nails, screws, hammers, and screwdrivers) are purchased similarly from each state. What are the null and alternative hypotheses?

Group of answer choices

a. Ho: Some states have the same distribution of purchases.

Ha: All states do not have the same distribution

b. Ho: All states have the same distribution of purchases.

Ha: All of the states have a different distribution

c. Ho: All states have the same distribution of purchases.

Ha: Not all states have the same distribution

d. Ho: All states do not have the same distribution.

Ha: All states have the same distribution of purchases

Answer 1

As we know the null hypothesis always have equality sign

So answer might be

b. Ho: All states have the same distribution of purchases.

Ha: All of the states have a different distribution

or

c. Ho: All states have the same distribution of purchases.

Ha: Not all states have the same distribution

As there are more than two parameters, hence Anova is to be used

And as per Anova, alternative hypothesis is that average is not same for all the groups

Hence answer here is

c. Ho: All states have the same distribution of purchases.

Ha: Not all states have the same distribution
