3. In a sample of 200 racquetball players, 120 indicated they prefer Penn racquetballs, 75 favored Ektelon, and 5 were indifferent. We want to use the sign test to determine if there is evidence of a significant difference in the preferences for the two types of racquetballs. Hint: Use the continuity correction factor. Provide the hypotheses to be tested. Compute the mean. Compute the standard deviation. At a 5% level of significance, test to determine if there is evidence of a significant difference in a. b. с. d. the preferences for the two types of racquetballs. 3.
