<span>An outlier of a set of data is a data value that is too small or too large compared to other values in the set of data.
Range of a set of data is the difference between the largest data value and the smallest data valu in the set of data.
Range of 23, 23, 25, 27, 34, 34, 35, 41, 45, 45, 78 is 78 - 23 = 55
When the outlier 78 is removed, the range of the data set 23, 23, 25, 27, 34, 34, 35, 41, 45, 45 is 45 - 23 = 22
Thus, when the outlier 78 is removed, the range of the data set decreases by 55 - 22 = 33.
Therefore, the correct answer to the question "The outlier, 78, is removed from the data set shown.
23, 23, 25, 27, 34, 34, 35, 41, 45, 45, 78
How does this affect the range?" is "The range is decreased by 33." (option D).</span>
For each time Mookie Betts went to bat, there were only two possible outcomes. Either he got a base-hit, or he did not. The probability of getting a hit on each at-bat is independent of any other at-bat. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
His average was 0.352.
This means that
Assume he has five times at bat tonight in the Red Sox-Yankees game.
4y+2x=14 ==> multiply this 1st equation by (-1) => -4y-2x=-14 Now add it up to the 2nd equation -4y-2x=-14 2y+2x=10 -------------- And now add them up -2y +0x=-4 ==> -2y=-4==> 2y = 4 & y=2 Last step: plug y into any equation & you will find x=3
