Answer:
Option C) 5.62 points
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 20
Sample mean score = 64
Sample standard deviation, s = 12
Degree of freedom =
We have to calculate margin of error for a 95% confidence interval.
Formula for margin of error:
Putting the values, we get,
Thus, the correct answer is
Option C) 5.62 points
<span>(a) Triangles ABC and PQR are similar triangles since they both share 2 congruent angles and therefore their 3rd angle is also congruent. So the triangles are similar due to the AAA similarity theorem.
(b) The area of triangle PQR is 1 million times larger than the area of triangle ABC. This can be shown since the area of a triangle is 1/2 base times height. You can show that the base of triangle PQR is 1000 times larger than the base of triangle ABC. And since all the sides are in proportion to each other, the height of triangle PQR is also 1000 times larger than the height of triangle ABC. And since 1000 times 1000 equals 1,000,000 or 1 million, the area of triangle PQR is 1 million times larger than triangle ABC.</span>
To get the store from which there's a likelihood of paying $18.75 for a pair shoes we consider the median of the data sets, which can represent the center of the measure of dispersion. This gives us store as the most likely store among the stores given from which you'll pay the stated price. This is because it's median is approximately $19.5
