Help!!! An ecommerce company claims that 67% or more graduate students have bought merchandise online. A consumer group is suspicious of the claim and thinks the proportion is lower than 67%. A random sample of 65 grad students show that only 37 have ever done so. Is there enough evidence to show that the true proportion is lower than 67%? Conduct the test with a=.10 and report in context the problem.

This is I think a one direction t test. The number who use it is not useful. You want to know the percent which is about 57 percent. The alternative hypothesis is that it its below 67%. You would have to run the test and find p to answer the question.
An alternative way to do this would b a test of proportions.
