The priority value is a numeric value that is an integer in the set of real numbers (can be negative, zero, or positive)

The billable status is basically a binomial: either billable or nonbillable.

The null hypothesis would be "priority value has no relationship to billable status."

The alternative hypothesis would be "priority value shows a clear relationship to billable status."

Here is the dataset, sorted ascending by priority (1st column). Clearly NB = nonbillable, B = billable

I was thinking a chi-square test could be done, but the other data is binomial. Looking elsewhere there was talk about "logistic regression," but I don't see how that figures.

Anyone want to suggest what I should look at?
