Solution:
Given data set is 1,1,3,4,6,7,30
An outlier is an extreme value (extremly low or high) compared to the other values in the data set.
Here, in the given data set 30 is an extremely high value and deviates from the pattern of other values in the data set.
Hence 30 is an outlier.
in the following set of scores, which score is an outlier. 1,1,3,4,6,7,30
Which of the following three test scores is the highest relative score? a score of 62 on a test with a mean of 72 and a standard deviation of 7.8 a score of 111 on a test with a mean of 130 and a standard deviation of 17.9 a score of 608 on a test with a mean of 720 and a standard deviation of 119.3 All scores are relatively equal.
7. z-scores and standardized scores Is a z-score a standardized score? No Yes Consider the following distribution of scores with a mean of 50 and a standard deviation of 10. For the letters A, B, C, and D in the boxes beneath the ine labeled "z" give the z-scores corresponding to each position in the distribution. One z-score is already filled in (-1) Suppose you also want to standardize these scores to a "k" scale where the mean of k...

17) The higher the bowling score the better. The lower the golf score the better. Assume both are normally distributed a) Suppose the mean bowling score is 155 with a standard deviation of 16 points. We will give a trophy for the best 5% of scores. What score must you get to receive a trophy? Suppose the mean golf score is 77 with a standard deviation of 3 strokes. We will give a trophy for the best 5% of scores....
