Question

Question 7 3 pts Provide the following information: A. Identify the hypothesis test as being two-tailed, left-tailed, or right-tailed. B. Find the p-value to within 3 decimal places. C. Using a significance level of a = 0.05, do we reject Ho or fail to reject Ho? The test statistic of z=0.20 is obtained when testing the claim that p 2 0.39. A. Tail: two, left or right B. P-value: C. Reject or Fail to Reject the null HTML Editora

Answer 1

A) Right- tailed

As the claim P≥0.39 i.e. the alternative hypothesis is right tailed ( as it contains greater than sign) so, the hypothesis test is right tailed.

B)As alternative hypothesis is right tailed so,

P-value= P( Z≥0.20)= 1-P( Z<0.20)= 1- 0.5793= 0.4207

( Using normal table)

C) P- value(= 0.4207 ) >alpha(=0.05) so, we don't reject H0.

Or

Fail to reject the null hypothesis.
