Enormous State University has an MPA program. The MPA director is concerned with the small number of MPA students who are being awarded Presidential Management Internships (PMIs). She thinks that this might be because MPA students lack interviewing skills. To experiment with this notion, 10 of the 20 PMI nominees are sent to a special interviewing workshop; the other 10 do not attend the workshop. Seven of the ten attending the workshop receive PMIs, and three of those not attending the workshop receive PMIs. Present a hypothesis and a null hypothesis, and evaluate them. State your conclusion in plain English.
