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.

State the null and alternative hypotheses for the test. Compute the test value. Compute the p-value. Find the area that corresponds to z = - 2.53. The area is 0.0057. So, the P-value is 2(0.0057)=0.0114. Make a decision whether to reject or not to reject the null hypothesis. Is ? Yes, we reject the null hypothesis. Summarize the conclusion.

State the null and alternative hypotheses. This question is similar to #19 and #24 above, but there is a subtle difference in the language that suggests an upper tail test instead of a two-tailed test. Note that management seems to be concerned only with the possibility that the true mean is greater than the null-hypothesized value of $160; in ...

Tests of Hypotheses Based on a Single Sample. A hypothesis is a claim or statement either about the value of a single population characteristic or about the values of several population characteristics. Statistical testing involves two complementary hypotheses: H0: null hypothesis. Ha :alternative …
