Explanation / Answer

a ) Decision rul is that if p value > level of significance then we rejet H0, otherwise we do not reject H0,

Here your P value = 0.06

And level of significance = 0.05

So, here P value > level of significance ,

So, here do not reject H0 (null hypothesis )

So, Option B is correct , We would decide not to reject null hypothesis , We would not have sufficient evidence that the population mean is different from 0.

b)

Type I error is reject null hypothesis when it is true .

And Type II error is do not reject null hypothesis when it false .

Here we do not reject H0, That is population mean is 0.

So, if decision in a is an error , so Type II error is happened .

c) If significance level = 0.1

Then P value < 0.1 , So we reject null hypothesis ,

And if it is an error , so Type I error would happen .

So, option A is correct .

If significance level is 0.1, then we would reject null hypothesis , and decision is an error then it would be Type I error .
