2) A sociologist was interested in the decline of racial discrimination in a particular geographical region from the 1960s to present. The number discrimination cases in this area were counted in 1960, and the average number of discrimination cases back then was approximately 110. A random sample of cities was obtained this month in the same area, and the average number of discrimination cases was approximately 47. Is there enough evidence to suggest that discrimination has significantly declined since the 1960s? Std. Deviation Std. Error Mean N.
