Test the claim that a population proportion is less than 0.8. A random sample of 71 trials yields 53 successes. Use a = 0.05. 1. To confirm that the sample is large enough, there must be at least 5 successes and 5 failures.

Suppose we are interested in investigating the mean of a normally distributed population. As part of the investigation, we intend to draw a sample of 1400 observations from this population and carry out a test of the null hypothesis Ho : µ =450 against a two-sided alternative hypothesis. Suppose that in reality, the population mean is 450. On average, what will the p-value equal? (Give your numeric response to at least 3 decimal places.

Suppose there is a claim that a certain population has a mean, 4, that is different than 5. You want to test this claim. To do so, you collect a large random sample from the population and perform a hypothesis test at the 0.05 level of significance. To start this test, you write the null hypothesis H, and the alternative hypothesis H1 as follows. Ho: u=5 H: H=5 Suppose you also know the following information. The critical values are -1.960 and 1.960 (rounded to 3 decimal places). The value of the test statistic is 2.574 (rounded to 3 decimal places).
