Answer:
Sample mean =119.42
Median = 92
25% trimmed mean = 102.42
10% trimmed mean = 95.69
Step-by-step explanation:
Data in increasing order :
12 13 20 23 31 35 40 43 48 49 58 62 66 67 69 71 73 77 78 79 82 85 86 89 91 93 97 99 101 105 106 106 112 117 124 135 139 141 147 159 161 168 183 207 249 262 289 323 388 513
Total no. of observations = 50
Sample mean =
= = 119.42
Median: Since we have even number of observation
Median = =
= 92
10% Trimmed Mean: We remove 5 values from each side
Trimmed set = 35 40 43 48 49 58 62 66 67 69 71 73 77 78 79 82 85 86 89 91 93 97 99 101 105 106 106 112 117 124 135 139 141 147 159 161 168 183 207 249
Trimmed mean = =
= 102.42
25% Trimmed Mean: We remove 12 values from each side.
Trimmed set = 66 67 69 71 73 77 78 79 82 85 86 89 91 93 97 99 101 105 106 106 112 117 124 135 139 141
Trimmed mean = =
= 95.69
Answer:
20%
Step-by-step explanation:
There is a 20% chance you get selected for researching China because 5 out of 25 spaces are ones for researching China.
Yes it does include the test point (0, 0)
- equation: y > -3x -5
- y > -3(0) -5
- y > -5
- y > -3x -5
<u>switch sides</u>
- -3x - 5 < 0
- -3x < 5
<u>Multiply both sides by -1 reverses the inequality</u>
- x > -5/3
Thus, the following (0, 0) comes under the following x > -5/3 and y > -5
