    In a test of hypothesis, the null hypothesis is that the population mean is equal to 90 and the alternative hypothesis is that the population mean is not equal to 90. The test is to be made at the 10% significance level. A sample of 100 elements selected from this population produced a mean of 84 and a standard deviation of 8. What is the value of the observed test statistic, z?

    In performing a hypothesis test where the null hypothesis is that the population mean is 4.8 against the alternative hypothesis that the population mean is not equal to 4.8, a random sample of 25 items is selected. The sample mean is 4.1 and the sample standard deviation is 1.4. It can be assumed that the population is normally distributed. The observed "t" value for this problem is _______.

    Suppose that we are testing the null hypothesis that μ = 68 versus the alternative that μ < 68. We take a sample of size 36 and find a sample average of = 63.4 and a sample standard deviation of s = 12.6. Determine the value of the test statistic for the hypothesis test of one population mean. t = -2.19 t = -0.37 t = 0.37 t = 2.19

    1. You want to test whether you can reject the null hypothesis that a population mean is greater than or equal to 10. To do this, you collect a random sample of size 500 from the population, and you calculate that the sample mean and sample standard deviation are 8.6 and s, respectively. Which of the following is true? a. If s is any value between 11 and 13, you can reject the null hypothesis at the 5% significance level....
