A random sample of the ages of 18 brides and their grooms showed that in 9 of the pairs the grooms were older, in 1 pair they were the same age, and in 8 pairs the bride was older. Perform a sign test with a significance level of

=0.05 to test the hypothesis that grooms tend to be older than their brides.

I need help solving this by finding the test statistic and p-value. Is there any way to input this in statcrunch or ti-84
