Answer:
Decision rule: Do not reject ; we cannot conclude that the mean differs from zero
Step-by-step explanation:
From the given information:
The null hypothesis and alternative hypothesis is given as:
And the 99% confidence interval for the population mean is: [−3.79, 5.86]
The significance level ∝ = 1 - 0.99 = 0.01
We will notice that the 99% confidence interval for the population mean contains the null hypothesis mean value which is equal to zero.
Thus, we do not reject the null hypothesis at the significance level ∝ = 0.01
∴
Decision rule: Do not reject ; we cannot conclude that the mean differs from zero
F(x) = q x 1.025(5)
f(x) = 5.125q
Not sure what the options are. This is the best I can do for an answer<span />
