Answer: The SST for the data set is 8.
Step-by-step explanation:
Since we have given that
Coefficient of determination (R²) = 0.25
SSE for the data = 6
SST = ?
As we know the formula for coefficient of determination:
Hence, the SST for the data set is 8.
Answer:
.
Step-by-step explanation:
The minimum and maximum value of over all real
are
and
, respectively. Hence, the maximum and minimum value of
would be:
The midline equation of a sine wave is a horizontal line that is right in the middle of maximum and minimum -values of that sine wave. In the sine wave in this question, the average of the maximum and minimum
-values is
. Hence, the midline equation of this sine wave would be
.
