Expert Solution

H0 : The means are all equal.

H1 : The means are not all equal.

F(2,12) at 0.05 level of significance


=3.8853

As calculated F=4.9655>3.8853

So, H0 is rejected, Hence there is significant differentiating between samples and the means are not all equal.

State whether each statement is true or false? Ho: u=150 H1: u (not equal to) 150 5% significance level A.) Rejection region= t>0.03 B.) If true population mean is 150 . Then the propability its even more is 0.03. C.) since p vaule is less than 0.05 we reject Ho at a 5% significance level D.) If 90 % CI wa caculated using the same data.150 would be inside the confidence interval.

To test Ho: ? = 400 versus H1: ? > 400, a simple random sample of n = 100 is obtained. Assume the population standard deviation is 80. If the researcher decides to test this hypothesis at the ?? = .05 level of significance, compute the probability of making a Type II Error if the true population mean is 420. What is the power of the test?
