Answer:
- The variation in the sample means makes it possible to make predictions about the population mean.
- The actual population mean is greater than 236.
- The actual population mean is less than 245.
Step-by-step explanation:
<u>Sample data</u>
- 1 2 3 4 5 6
- 240 236 245 243 238 242
<u>Mean = sum of sample data/sample frequency</u>
- (240+236+245+243+238+242)/6 = 240.67
Answer choices:
The variation in the sample means makes it possible to make predictions about the population mean.
The actual population mean is greater than 236.
The actual population mean is less than 245.
The actual population mean is greater than 245
The population mean is the average of the sample means.
For the first one the answer is 17
34÷2=17
Answer:
False (under assumption T(2,-3) means move it right 2 units and down 3 units).
Step-by-step explanation:
The statement is false.
T(2,-3) means move the point right 2 (so plus 2 on the x-coordinate) and down 3 units (so minus 3 on the y-coordinate).
So (1,6) will become (1+2,6-3)=(3,3) after the translation.
The point (1,12) will become (1+2,12-3)=(3,9).
If the statement were "Under the translation T(2,-3) the point (1,12) will become (3,9)", then it would be true.
Or!
If the statement were "Under the translation T(2,3) the point (1,6) will become (3,9)", then it would be true.
