If a null hypothesis is rejected against an alternative at the 5% level, then using the same data, it must be rejected against that alternative at the 1% level. False. Recall that we reject the null hypothesis when the p-value is smaller than alpha.

The alternate hypothesis is a logical alternative to the null. It is a statement of what the test is set up to establish and generally, a statement of the anticipated outcome of the test In this case the hypothesis would be the following.

Introduction to Hypothesis Testing Table Identify whether each research scenario listed in the left column of the top of the matrix, would be a one- or two-tailed test and then justify your decision. For each research scenario in the bottom of the matrix, write what the null and alternative hypotheses would be.

Alternative Hypothesis: The alternative is that the variable does contribute and should remain in the model: H1: βk 0. Test Statistic: which is found on any regression printout. Sampling Distribution: Under the null hypothesis the statistic follows a t-distribution with n - p degrees of freedom.

A claim is made that p = .70. Set up the null and alternative hypothesis to test this claim. Calculate the test statistic for the test you carried out in part b. Find the rejection region for the test if a = .01. Use the results from c and d to draw the appropriate conclusion. 8.95 (5 points) Suppose you want to test using against using a = .05.

There are two types of statistical hypotheses: the null hypothesis states that there is no difference, and the alternative hypothesis specifies a difference. The z test is used when the population standard deviation is known and the variable is normally distributed or when ( is not known and the sample size is greater than or equal to 30.

Alternative Hypothesis. and is denoted, HA. When setting up hypotheses, the usual practice is to make the Alternative Hypothesis the statement about the parameter that you would like to show, then make the Null Hypothesis the opposite of this statement.

The alternative hypothesis (H A) represents an alternative claim under consideration and is often represented by a range of possible parameter values.Even if we fail to reject the null hypothesis, we typically do not accept the null hypothesis as true.
