Answer:
The appropriate alternative hypothesis if he wanted to substantiate his suspicion would be
Step-by-step explanation:
At the null hypothesis, we test that the mean is equal to a certain value.
At the alternate hypothesis, we test that the mean is different, less than or more than the mean value tested at the null hypothesis.
The historical U.S. mean unemployment insurance benefit was reported to be $238 per week.
This means that the null hypothesis is:
A researcher in the state of Virginia anticipated that sample data would show evidence that the mean weekly unemployment insurance benefit in Virginia was above the national level.
This means that the alternate hypothesis is:
Values of x and y will be 12 and 5 respectively.
It's given in the question,
- Three points Q, R and S are collinear.
- Coordinates of Q → (2, 0)
- Coordinates of R → (8, 3)
- Coordinates of S → (x, y)
- QR : RS = 3 : 2
Since, expression for the coordinates of a point (h, k) which divides the segment joining points and
in the ratio of m : n is given by,
h =
k =
Since, R is a point on segment QS dividing in the ratio of 3 : 2, coordinates of R will be,
Similarly,
Therefore, values of x and y will be 12 and 5 respectively.
