The null and alternative hypotheses are given. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed
NNADVOKAT [17]

Correct clear question is;

The null and alternative hypotheses are given. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. What parameter is being tested? H_0: μ = 5 H_1: μ ≠ 5

Is the hypothesis test left-tailed, right tailed, or two tailed? A Left tailed B Right tailed C Two tailed

What parameter is being used? A population proportion B population mean C standard deviation

Answer:

A) C - Two tailed hypothesis

B) B - Population mean

Step-by-step explanation:

We are given the hypotheses to be;. Null Hypothesis; H_0: μ = 5

Alternative hypothesis; H_1: μ ≠ 5

From the alternative hypothesis, we can see that the critical area of distribution of the parameter being tested could either be less than 5 or greater than 5 due to the not equal to sign. This means it could either be left tailed or right tailed. Thus, it is a two tailed hypothesis.

From the hypothesis, we see that the symbol μ is being used.

In statistics, μ is generally used as a symbol to denote population mean.

Thus, parameter being used/tested is population mean

What is the constant of variation,k, of the direct variation,y=kx,through (5,8)
grigory [225]

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form \frac{y}{x}=k or y=kx

where

k is the constant of variation

in this problem we have

the point (5,8)

so

x=5\\y=8

substitute

\frac{y}{x}=k

\frac{8}{5}=k

therefore

<u>the answer is</u>

k=\frac{8}{5}

8<br> m_AHI = 13x +9, mZGHI = 137°,<br> and mZGHA = 8x + 2. Find x.<br> H<br> G
777dan777 [17]

Answer:

x = 6

Step-by-step explanation:

<GHA + <AHI = <GHI

(8x + 2) + (13x + 9) = 137

8x + 13x + 2 + 9 = 137

21x= 137 - 11

x = 126/21

x = 6
