k BFW Publishers To study vision impairment under the influence of illegal subtances, a group of 54 volunteers were used in a study. The volunteers each completed two tasks: they completed a vision test with and without googly goggles on. Googly goggles simulate the visual impairment that often occurs when a person is under the influence. The order in which they completed the vision tests was determined by a coin toss and the tests, while equally difficult, were different so that the first test did not assist them in earning better scores on the second test. The number of words they could correctly read was noted for each test. The mean difference (with goggles - without goggles) is -10.5 words with a standard deviation of 27.015 words. Do these data provide convincing evidence at the α = 0.05 level that wearing Googly goggles decreases the number of words that can be read, on average?
