(p ≠ 0.086)
c) Classify the hypothesis test as two-tailed, left-tailed or right-tailed
This is a two-tailed test, since there is no direction specified for the test. The solution discusses hypothesis testing and unemployment levels.
264010 Introduction to Hypothesis Testing Introduction to Hypothesis Testing
State the claim mathematically. Then write the null and alternative hypothesis. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed.
The two-tailed P value equals 0.0658
b. The two-tailed P value equals 0.0843, so the required one-tailed p-value is 0.0843/2 = 0.042155 This solution finds the p-value for each of the hypothesis-testing situations.
a) What is your null hypothesis? Alternate hypothesis?
Null Hypothesis H0: mean = 75
Alternate Hypothesis Ha: mean is not equal to 75
b) Is this a one-tailed or two-tailed hypothesis?
c) What is your obtained z?
choice questions on testing of hypothesis
A two-tailed hypothesis test at the 0.10 level of significance where the initial probability calculated for the test statistic is 0.047. (Don't forget to make the adjustment needed for the two tailed test.)
How would you arrive at a probability value (given in the z-score table) to reflect a two-tailed hypothesis? How would you arrive at a probability value to reflect a one-tailed hypothesis?
Indicate the type of test to be performed (left-tailed, right-tailed, or two tailed)
B) Provide a statement in terms of the hypothesis testing process in this problem that would signify a Type I Error has been committed.
I will provide the null and research hypotheses and Type 1 and Type 2 errors for both two-tailed and one-tailed hypothesis testing situations.
Is the alternative hypothesis one-tailed or two-tailed?
The alternative hypothesis is one tailed because it has a '<' sign in it.
d. What is the p-value?
