Determine the decision criterion for rejecting the null hypothesis in the given hypothesis test; i.e., describe the values of th

Olegator [25]

Answer:

The critical value for this case can be calculated using the t distribution with 7 degrees of freedom and the critical value would be a value who accumulates 0.1 of the area in the right of the distribution and the best decision based on the possible options would be:

c). Reject H0 if test statistic is greater than 1.895.

Step-by-step explanation:

The system of hypothesis for this case are:

Null hypothesis: $\mu_d = 0$

Alternative hypothesis: $\mu_d >0$

The statistic for this case is given by:

$t=\frac{\bar d -0}{\frac{s_d}{\sqrt{n}}}=\frac{3.125 -0}{\frac{2.911}{\sqrt{8}}}=3.04$

The degrees of freedom are given by:

$df=n-1=8-1=7$

The p value for this case can be calculated from this probability:

$p_v =P(t_{(7)}>3.4) =0.0057$

The critical value for this case can be calculated using the t distribution with 7 degrees of freedom and the critical value would be a value who accumulates 0.1 of the area in the right of the distribution and the best decision based on the possible options would be:

c). Reject H0 if test statistic is greater than 1.895.
