Given two dependent random samples with the following results:
Naddik [55]

Answer:

The null hypothesis will not be rejected.

Step-by-step explanation:

The hypothesis for the test is:

<em>H</em>₀: There is no difference between the two population means, i.e. <em>d</em> = 0.

<em>Hₐ</em>: There is a significant difference between the two population means, i.e. <em>d</em> ≠ 0.

Consider the Excel output attached.

The mean of the differences is, \bar d=-2.75.

The standard deviation of the differences is, S_{d}=4.268.

Compute the test statistic as follows:

t=\frac{\bar d}{S_{d}/\sqrt{n}}=\frac{-2.75}{4.268/\sqrt{8}}=-1.82

The degrees of freedom is, n - 1 = 7.

Compute the <em>p</em>-value as follows:

p-value=2\cdot P(t_{7}

The decision rule is:

The null hypothesis will be rejected if the p-value of the test is less than the significance level.

<em>p</em>-value = 0.112 > α = 0.02.

The null hypothesis will not be rejected.
