A lumber company is making boards that are 2697.0 millimeters tall. If the boards are too long they must be trimmed, and if they

are too short they cannot be used. A sample of 25 boards is made, and it is found that they have a mean of 2697.4 millimeters with a standard deviation of 10.0 . Is there evidence at the 0.1 level that the boards are either too long or too short? Assume the population distribution is approximately normal.
a. Determine the decision rule for rejecting the null hypothesis.
b. Make the decision to reject or fail to reject the null hypothesis.

A is your answer because when it says assume the population that means that you need to figure out what isn’t he hypothesis

Help with this please.
Ivanshal [37]

Answer:

  • True
  • True

Step-by-step explanation:

This question asks you to compare the coordinates of the vertex of each function.

__

The vertex of the function is its minimum, the point where the graph stops decreasing and starts increasing. It is the lowest point on the graph.

<h3>f(x)</h3>

The vertex is (-4, -1). The minimum is -1, located at x = -4.

<h3>g(x)</h3>

The vertex is (1, -25). The minimum is -25, located at x = 1. We know this is the minimum because there are no g(x) values that are lower (more negative).

<h3>comparison</h3>

The minimum of f(x), -1, is greater than the minimum of g(x), -25. TRUE

The x-value of f(x) at its minimum, -4, is less than the x-value of g(x) at its minimum, 1. TRUE

What is the volume of this triangular Pyramid photo attached
storchak [24]

To find the volume of a triangular pyramid, the formula is:

V=\frac{1}{3}(Area\text{ }of\text{ }thebase)(height)

So we start by finding the area of the base, which is in the shape of a right triangle in this case.

The area of a right triangle is equal to 1/2 x base x height.

\begin{gathered} A=\frac{1}{2}bh \\  \\ A=\frac{1}{2}(5)(6) \\  \\ A=15\text{ square feet} \end{gathered}

We use this area to find the volume.

\begin{gathered} V=\frac{1}{3}Ah \\  \\ V=\frac{1}{3}(15)(6) \\  \\ V=30\text{ cubic feet} \end{gathered}

The volume of the triangular pyramid is 30 cubic feet.
