Using it's concept, the relative frequencies are given as follows:

  • Republican residents of County 1: 37.9%.
  • Democratic residents of County 1: 62.1%.
  • Total Republican residents: 58.9%.
  • Total Democratic residents: 41.1%.

<h3>What is a relative frequency?</h3>

A relative frequency is given by the<u> number of desired outcomes divided by the number of total outcomes</u>.

In County 1, we have that there are 6,520 residents, out of which 4,050 are Democratic and 2,470 are Republican, hence the relative frequencies are given as follows:

  • Republican residents of County 1: 2470/6520 = 37.9%.
  • Democratic residents of County 1: 4050/6520 = 62.1%.

In total, there are 24,505 residents, out of which 10,075 are Democratic and 14,430 are Republican, hence the relative frequencies are given as follows:

  • Total Republican residents: 14430/24505 = 58.9%.
  • Total Democratic residents: 10075/24505 = 41.1%.

If we think about a normal curve / bell curve and the 68-95-99.7 rule, we know that the majority of data will lie within 1, 2, or 3 standard deviations from the mean. The mean is in the center of the curve, and to each side of the mean, 34% of the data lies 1 standard deviation on either side of the mean. Therefore, we need to add and subtract one standard deviation from the mean.

85 + 12 = 97

85 - 12 = 73

Correct Answer: B. 73 - 97

Hope this helps!! :)
