Suppose there is a claim that a certain population has a mean, u, that is 6 or more. 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 0.10 level of significance. To start this test, you write the null hypothesis Ho and the alternative hypothesis H, as follows. Ho u26 Hi u<6 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 -2.405 (rounded to 3 decimal places).

Suppose there is a claim that a certain population has a mean, µ, that is different than 7. 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.
