5.For ANOVA: the null hypothesis is: Mu1 = Mu2 = Mu3......etc T/F
6.For ANOVA: the alternative hypothesis is: Mu1 ≠Mu2 ≠Mu3......etc. T/F
Solution
5.For ANOVA: the null hypothesis is: Mu1 = Mu2 = Mu3......etc T
6.For ANOVA: the alternative hypothesis is: Mu1 ≠Mu2 ≠Mu3......etc. T
5.For ANOVA: the null hypothesis is: Mu1 = Mu2 = Mu3......etc T/F 6.For ANOVA: the alternative...
Question 1 For ANOVA: the null hypothesis is: Mu1 = Mu2 = Mu3......etc True False Question 2 For ANOVA: the alternative hypothesis is: Mu1 ≠Mu2 ≠Mu3......etc. True False Question 3 Both ANOVA and Chi square tests are always right tail tests True False Question 4 For ANOVA, you only complete a Tukey's means comparisons test if the overall F* value was significant (i.e., p<0.05) True False Question 5 Both F and Chi Square distributions vary with df True False Question...
If X and Y have the bivaraite normal distribution with mu1= 2, mu2= 5, sigma1= 3, sigma2= 6 and p=2/3. I’m tryin to find an expression for the correlation coefficient of U and V. Given U=X+Y and V=X-Y
11. What is the null hypothesis for a t-test for two independent groups? a. If mul and mu2 are the population means of the two groups, then the null hypothesis is Ho: mul-mu2=0. b. If sl and s2 are the population standard deviations of the two groups, then the null hypothesis is Ho: sl-s2=0. 12. Differentiate between a data set that should be analyzed using a paired t-test from a data set that should be analyzed using a t-test for...
STEP 2 State the Null and Alternative (Research) hypotheses NULL Hypothesis ALTERNATIVE Hypothesis Is this a one or two tailed test (if a one tailed test, what direction)? STEP 3 Define the elements of the problem What is the population or populations of interest? What is the sample? 3. The President claims that 100,000 jobs were created last month. You don't believe this claim is true, so you examine a sample of 1,000 records from the Bureau of Labor Statistics...
(20) 1. Complete the ANOVA table (9 points), state the null and alternate hypothesis in symbols and in words (6 points). Copy the results using technology and use words to describe how f relates to the p value and what the results indicate (5 points). Girls from four different soccer teams are to be tested for mean goals scored per game. The entries in the table are the goals per game for the different teams as shown in the table...
6. True or False? The null hypothesis indicates that there is no difference while the alternative hypothesis indicates that there is a difference between the means of two groups.
Q7) A hypothesis test is to be performed with a Null hypothesis and an alternative hypothesis , the population standard deviation is σ=3.0, the sample size is 30, and the significance level is α=0.025. What is a type I error? (1 mark) What is the chance of making a type I error in the above test? (1 mark) What is a Type II error? (1 mark) What value would the sample mean have to be greater than to reject Ho? (2 marks) It is...
3. A P-value is always computed assuming that the: A) alternative hypothesis is true. B) alternative hypothesis may be true. C) null hypothesis may be true. D null hypothesis is true. 3. A P-value is always computed assuming that the: A) alternative hypothesis is true. B) alternative hypothesis may be true. C) null hypothesis may be true. D null hypothesis is true.
Decide whether or not to reject the null hypothesis in favor of the alternative hypothesis at significance level α = 0.05 α=0.05 based on the following information: n = 32 n=32, HA : μ ≠ 200 H A :μ =200, T = 0.001 T=0.001. I recommend that you sketch the area that represents the p-value.
Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method. Use either the T Calculator or the Normal Calculator to compute the P-value of the following test statistics. (a) The test statistic in a two-tailed is z = 1.39. Round to four decimal places. (b) Find the P-value for a right-tailed test with n = 27 and test statistic t = 1.502. Round to...
