If the null hypothesis of an experiment is “The true mean weight of the geese is greater than 40 pounds” what is the alternate h

Answer:

The true average weight of geese is less than or equal to 40 pounds

Step-by-step explanation:

The null hypothesis and the alternative hypothesis are two mutually exclusive statements or hypotheses that are made about a population. The purpose is to find out if, through a study of the data, sufficient evidence is obtained to reject one and accept another

The null hypothesis is denoted as $H_0$ and the alternative hypothesis as $H_1$

As they are two mutually exclusive statements then if

$H_0$ : "The true average weight of the geese is greater than 40 pounds"

the alternative hypothesis must be the opposite of the null hypothesis

$H_1$ : "The true average weight of geese is less than or equal to 40 pounds"

<h3>Answer: 7.1</h3>

=========================================================

Explanation:

The two points are (x1,y1) = (1,3) and (x2,y2) = (8,4)

Use the distance formula to get,

$d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(1-8)^2 + (3-4)^2}\\\\d = \sqrt{(-7)^2 + (-1)^2}\\\\d = \sqrt{49 + 1}\\\\d = \sqrt{50}\\\\d = \sqrt{25*2}\\\\d = \sqrt{25}*\sqrt{2}\\\\d = 5\sqrt{2}\\\\d \approx 7.0710678\\\\d \approx 7.1$

Alternatively, you can plot the two points A(1,3) and B(8,4) on the same xy grid. Then plot point C(8,3). Note that C has the same x coordinate as B, and the same y coordinate as A. Triangle ABC is a right triangle, where the 90 degree angle is at point C. The distance from A to B is the same as finding the length of AB, which is the hypotenuse.

This means we can apply the pythagorean theorem to find the hypotenuse AB. The distance formula is a modified version of the pythagorean theorem. Refer to the diagram below.
