The JFK Assassination More than 40 years after the assassination of John F. Kennedy, a FOX News poll shows most Americans disagree with the government’s conclusions about the killing. The Warren Commission found that Lee Harvey Oswald acted alone when he shot Kennedy, but many Americans are not so sure. Do you think that we know all the facts about the assassination of President John F. Kennedy or do you think there was a cover-up? Here are the results from a poll of 900 registered voters nationwide:7
| We Know All the Facts | There Was a Cover-Up | (Not Sure) |
Democrats | 42 | 309 | 31 |
Republicans | 64 | 246 | 46 |
Independents | 20 | 115 | 27 |
a. Do these data provide sufficient evidence to conclude that there is a difference in voters’ opinions about a possible cover-up depending on the political affiliation of the voter? Test using a = .05.
b. If there is a significant difference in part a, describe the nature of these differences.
