<u>Answer:</u>
1 and 5 are correct.
<u>Step-by-step explanation:</u>
1. The mean is affected by outliers. - TRUE
(the mean is the average so each of its values affect it.)
2. The mean is always a more accurate measure of center than the median. - FALSE
(the mean gives a better idea of the values while the the central values for normal distributions are described using the median value.)
3. Removing an outlier from a data set will cause the standard deviation to increase. - FALSE
(it makes the data set more normal by reducing the standard deviation, not increasing it. )
4. If the data set’s distribution is skewed, then 95%of its values will fall between two standard deviations of the mean. - FALSE
(the 68-95-99.9 rule works for the normal distribution, but the skewed distribution.)
5. If a data set’s distribution to skewed to the right, its mean will be larger than its median. - TRUE
(the mean is always pulled towards the direction of the skewness.)
Part A:
Given that <span>her score is always in between the lowest score and the highest score shown.
</span>From the figure, Lee's lowest score wss 4 1/2 and her highest score was 5.
From the cards given, the number in the card between 4 1/2 and 5 is 4 3/4.
Part B:
Given that <span>her score is always in between the lowest score and the highest score shown.
</span>From the figure, Lee's lowest score wss 0.325 and her highest score was 0.35.
From the cards given, the number in the card between 0.325 and 0.35 is 0.349.
Part C:
Given that <span>her score is always in between the lowest score and the highest score shown.
</span>From the figure, Lee's lowest score wss 0.35 and her highest score was 0.375.
From the cards given, the number in the card between 0.35 and 0.375 is 0.365.
Part D:
Given that <span>her score is always in between the lowest score and the highest score shown.
</span>From the figure, Lee's lowest score wss 0.2 and her highest score was 0.225.
From the cards given, the number in the card between 0.2 and 0.225 is 0.221.
Part E:
Given that <span>her score is always in between the lowest score and the highest score shown.
</span>From the figure, Lee's lowest score wss 2 3/4 and her highest score was 3.5.
From the cards given, the number in the card between 2 3/4 and 3.5 is 2.751.
