A hypothesis will be used to test that a population mean equals 5 against the alternative that the population mean is less than

Oksi-84 [34.3K]

Answer:

For the significance level of 0.01, the critical value for the test statistic is 2.326.

Step-by-step explanation:

Null hypothesis: population mean equals 5.

Alternate hypothesis: population mean is less than 5.

The test is a one-tailed test because the alternate hypothesis is expressed using less than.

For a one-tailed test, the critical value of the test statistic for the significance level of 0.01 is 2.326.

Can anyone please help I am struggling with math and Noone wants to help me and I want to learn so does anyone understand HOW u

vlada-n [284]

Answer:

Step-by-step explanation:

256 = 16×16=4×4×4×4 = 4^4

X^4-4^4 = (x^2)^2 - (4^2)^2

Using algebraic identity a^2-b^2 = (a+b)(a-b)

We get (x^2+4^2)(x^2-4^2)

(x^2+4^2)(x+2)(x-2)

Coordinates (x, y)
Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

<u>Step 1: Define</u>

Point (2, 5)

Point (-3, 7)

<u>Step 2: Identify</u>

x₁ = 2, y₁ = 5

x₂ = -3, y₂ = 7

<u>Step 3: Find slope </u><em><u>m</u></em>

Simply plug in the 2 coordinates into the slope formula to find slope<em> m</em>

Substitute in points [Slope Formula]: $\displaystyle m=\frac{7-5}{-3-2}$
[Slope] [Fraction] Subtract: $\displaystyle m=\frac{2}{-5}$
[Slope] [Fraction] Rewrite: $\displaystyle m=\frac{-2}{5}$
