A variety of research results suggest that visual images interfere with visual perception. In one study, Segal and Fusella (1970) had participants watch screen, looking for a brief presentation of a small blue arrow. On some trials, the participants were also asked to form a mental image (for example, imagine a volcano). The results for a sample of n = 10, show that participants make an average of 7.5 more errors while forming images than while not forming images. The difference scores had SS = 70. Do the data indicate a significant difference between the two conditions? Use a one-tailed test with α = 0.01. (Use the four logical steps in hypothesis testing)

. A variety of research results suggest that visual images interfere with visual perception. In one study, Segal and Fusella (1970) had participants watch screen, looking for a brief presentation of a small blue arrow. On some trials, the participants were also asked to form a mental image (for example, imagine a volcano). The results for a sample of n = 10, show that participants make an average of 7.5 more errors while forming images than while not forming images. The difference scores had SS = 70.
Do the data indicate a significant difference between the two conditions?
Use a one-tailed test with α = 0.01. (Use the four logical steps in hypothesis testing)
