Consider the following hypothesis test:
KengaRu [80]

Answer:

(a) t= -1.540

(b) 0.10 < p < 0.20

(c) Fail to reject H_o

Step-by-step explanation:

Given

H_o: =18       H_a: \ne 18

n = 48

\bar x = 17

\sigma = 4.5

Solving (a): The test statistic

This is calculated as:

t= \frac{\bar x - \mu_o}{\sigma/\sqrt n}

So, we have:

t= \frac{17 - 18}{4.5/\sqrt{48}}

t= \frac{- 1}{4.5/6.93}

t= \frac{- 1}{0.6493}

t= -1.540 --- approximated

Solving (b): Range of p value

First, calculate the degree of freedom (df)

df = n - 1

df = 48 - 1

df = 47

Using:

\alpha = 0.05 --- significance level

The p value at: df = 47 is:

p = 0.065133

and the range is:

0.05 * 2 < p < 2 * 0.10

0.10 < p < 0.20

Solving (c): The conclusion

Compare the p value to the level of significance value

We have:

p = 0.065133

\alpha = 0.05

By comparison:

p > \alpha

because:

0.065133 > 0.05

<em>Hence, the conclusion is: fail to reject </em>H_o<em></em>
