Answer:
The standard deviation of the sample mean is 16.98.
Explanation:
The standard deviation of the sample mean differences is given as by the difference of the 2 standard deviations.This is given as
Difference of standard deviations=21.2-17.6 = 3.6
Now the ratio of the difference to the largest standard difference is given as
Ratio=3.6/21.2=0.1698
Converting this into percentage as 0.1698x100=16.98
The standard deviation of the sample mean is 16.98.
The amendment that some Americans criticized as not going far enough to make suffrage universal was A. the Fifteenth Amendment, which granted the vote to African-American men. Around the period of the Civil War, campaigns for women's suffrage had begun to take hold. Many argued that the 15th Amendment should have expanded its scope and included women; however, the men responsible for the 15th Amendment feared that adding women to the mix could doom the amendment to failure. They argued that women were excluded in order to guarantee that at least African-American men be given the right to vote.
