Answer:
(a) Mean=74
(b) Median=70
(c) The best measure of center= Median.
Step-by-step explanation:
We have been given a data set of PSAT scores of Mrs. Turay's eight graders. We are asked to find mean and median of the given data set.
(a) Let us find mean of data set by dividing the sum of given scores by the number of students.
Therefore, the mean test score will be 74.
(b) Now let us find median of our given data set. We have been given that number of students is 10, therefore, our median will be the average of 5th and 6th term.
60, 62, 67, 69, 70, 70, 71, 75, 76, 120.
We can see that 5th term is 70 and 6th term is 70 as well.
Therefore, the median test scores will be 70.
(c) We can see that our data set has an outlier score as 120, which has increased the mean. Mean score is greater than median score. Since median is not affected by extreme value outliers, therefore, median will be the best measure of center for given test scores.

Step-by-step explanation:
we know that
The area of the circular path alone is equal to subtract the area of the circular garden from the area of the complete circle (circular garden plus circular path)
so
where
---> radius of circular garden
----> radius of the circular garden plus radius circular path
substitute
