The alternative hypothesis specifies any value less than 0.20. The table below lists possible alternative values, along with an estimate of the power of the 65 box test with against each alternative. These estimates of the power were obtained by simulating 1000 trials of 65 box tests (using ) for each alternative.

Alternative Hypothesis is to see if the groups are different. Read the Step by Step on pages 629-630. 8. What calculator command do you use to find the p value once you know the Chi-Squared statistic? Note: When we reject then there is strong evidence that changes have occurred between groups.

b) What is the null and alternative hypothesis associated with the t-statistic associated with x2? c) Graphically, illustrate the meaning of the p-value associated with the t-statistic for x3? At an α level of 0.05, do you reject or fail to reject the t-test? 15 points. 11. Explain the Gauss-Markov theorem.

x+b” the calculator calls it “y= a. ... Notice you need to know what the Alternative Hypothesis is to test it. For RegEQ do this: Go to Vars Y-Vars Function Y1 enter. This will enter Y1 on the RegEQ line. This will then enter the equation for a line in the string Y1 –This is so we can graph it if we want.

The rejection region (RR), also called a critical region, is the region in which the alternative hypothesis is true, the region beyond the critical value. The critical value is determined with a z or t value based upon the hypothesis ( or p. When the test statistic (the z or t computed based upon the sample data and the value of is found to be .

The alternative hypothesis is that they are not equally likely. A sample of birth records shows the following distribution. Day Sun. Mon. Tue. Wed. Thu. Fri. Sat. Births 13 23 24 20 27 18 15 Since there were a total of 140 births, under the null hypothesis 20 births per day would be expected.

List and explain the differences between a null hypothesis and an alternative hypothesis. Discuss the meaning of statistical significance. Use the Inference Toolbox to conduct a large sample test for a population mean. Compare two-sided significance tests and confidence intervals when doing inference.

1. Explain the difference between a one-sided alternative hypothesis and a two-sided alternative hypothesis? One sided means a specific direction such as greater than or less than. A two-sided alternative means either direction, greater than or less than. 1-sided < or > 2 sided ≠ 2. Write the steps to follow for significance testing.

Given that a researcher has the null hypothesis that μ=μ0 and alternative hypothesis that μ=μ1≠ μ0, and that the population variance is known as σ2. Also, he knows that he wants to reject the null hypothesis at a significance level of α which gives a corresponding Z score, called it Zα/2.
