A Type I error is making a correct decision in a hypothesis test. when a correct null hypothesis is rejected in a hypothesis test. usually not controlled for in a hypothesis test. when a correct alternative hypothesis is rejected in a hypothesis test. both (c) and (d) are true.
Suppos v re is a daim that a certain population has a mean, u, that is 5 or less. You want to test this daim. To do so, you collect a large random sample from the population and perform a hypothesis test at the 0.10 level of siqnificance. To start this test, you write the null hypothesis H, and the alternative hypothesis H, as follows. Ho: HS5 H: u>5 Suppose you also know the following information. The critical value is 1.282 (rounded to 3 decimal places). The value of the test statistic is 2.567 (rounded to 3 decimal places). (a) Complete the steps below to show the rejection region(s) and the value of the test statistic for this test. Normal Distribution Step 1: Select one-talled or two-tailed. O One-talled O Two-tailed Step 2: Enter the critical value(s). (Round to 3 dedmal places.) 0.2 Step 3: Enter ie test statistic. (Round to 3 delimal places.) (b) Based on your answer to part (a), choose the correct statement. O The value of the test statistic lies in the rejection region. o The…

A scientist has read that the mean birth weight of babies born at full term is 7.4 pounds. The scientist has good reason to believe that the mean birth weight of babies born at full term, u, is different from this value and plans to perform a statistical test. She selects a random sample of birth weights of babies born at full term and finds the mean of the sample to be 7.8 pounds and the standard deviation to be 1.5 pounds. Based on this information, complete the parts below. (a) What are the null hypothesis H, and the alternative hypothesis H, that should be used for the test? Ho :0 O
