Answer:
The point estimate of the population mean for the confidence interval of (15,32) is 23.5
Step-by-step explanation:
We are given the following information in the question:
Confidence interval for population mean is (15, 32).
We have to find the point estimate for population mean.
Formula:
The point estimate of the population mean for the confidence interval of (15, 32) is 23.5
Answer:
Option d is correct.
Both the x and y coordinates of the point on δa'b'c' have opposite signs from the corresponding points on δabc.
Step-by-step explanation:
The rule of 180 degree rotation about the origin is:
Since a Rotation of a point through 180°, about the origin when a point a(h, k) is rotated about the origin through 180° in anticlockwise or clockwise direction.
then, By the rule of 180 degree rotation;
so, it takes the new position i.e,
Therefore, both the x and y coordinates of the point on δa'b'c' have opposite signs from the corresponding points on δabc.
