There are three samples as per question, If we arrange chronologically the samples will be
-8, -6, 11
Now looking at the present data, the range (Diff between highest & lowest sample) is (11-(-9)) = 19. Median is -6 (the middle figure), however as per question we need to add one sample, median & range will not change.
The range is fixed which is 19.
The figure must be between -6 & 11.
Considering the new figure as "X". Hence (-6 + X)/2 = -6, Hence solving the equation, X = -6.
Hence the Ans : New sample will be -6.
The sequence of sample is -8, -6, -6, 11.
Ans : -6
Given the sample -6 11, add one more sample value that will neither change the median...
Given the sample -6 11, add one more sample value that will neither change the median nor the range. Round to two decimal places as necessary. If this is not possible, indicate "Cannot create sample"
goven the sample 2, -10, 2, add one more sample value that will neotger change the mode or the range

Find the (a) mean, (b) median, (c) mode, and (d) midrange for the data and then (e) answer the given question.Listed below are the jersey numbers of 11 players randomly selected from the roster of a championship sports team. What do the results tell us? 9 94 58 38 42 73 46 15 88 64 7a. Find the mean. The mean is _______ . (Type an integer or a decimal rounded to one decimal place as needed.) b. Find the median. The...
Find the mean, median, and mode of the following data. If necessary, round to one more decimal place than largest number of decimal places given in the data. 8.1 Measures of Center 8/12 Correct Rate of Fatal Alcohol Impaired Car Crashes per 100 Million Vehicle Miles of Travel 0.58 0.71 0.70 0.70 0.49 0.51 0.68 0.63 0.68 0.70 0.66 0.79 0.55 0.70 0.42 0.32 0.52 0.59 0.39 0.52
10. Construct a sample (with at least two different values in the set) of 4 measurements whose mean, median, and mode are equal. If this is not possible, indicate "Cannot create sample". Selecting a checkbox will replace the entered answer value(s) with the checkbox value. If the checkbox is not selected, the entered answer is used. Cannot Create Sample
One hundred teachers attended a seminar on mathematical problem solving. The attitudes of a representative sample of 12 of the teachers were measured before and after the seminar. A positive number for change in attitude indicates that a teacher's attitude toward math became more positive. The 12 change scores are as follows:4; 9; −1; 2; 0; 5; −3; 1; −1; 6; 3; −2What is the mean change score?Round your answer to two decimal places.xˉ= What is the standard deviation for this sample?Round your answer to two decimal places.s= What is the median change score? Find the change score...
