Assume that Data Set C depicts scores for 30 individuals who participated in a two-way independent groups design. Analyze the data using a two-way ANOVA and complete an ANOVA table reporting the relevant DD, df, MS, and Fs. Make sure to also report each of your critical values and indicate whether you would reject each of your three null hypotheses (i.e., main effect of A, main effect of B, interaction of A x B) Data Set C Variable B Variable...

Please: You may NOT use Excel, SPSS, or any other statistical software to get your answers. You must show all of your by-hand computations for full credit. assume you’re using an alpha of .05, and a two-tailed test, to make your decision about whether to reject the null hypothesis.

i need help with this question, please show work by hand no excel, spss thank you ! Assume you're using an alpha of 05, and a two-tailed test, to make your decision about whether to reject the null hypothesis. Assume that 18 subjects received one of three treatments and produced the data reported in Data Set B. Conduct a one-way ANOVA to see if the means of the three treatments are different on a statistically significant level. Complete an ANOVA...
A study compared three display panels used by air traffic controllers. Each display panel was tested for four different simulated emergency conditions. Twenty-four highly trained air traffic controllers were used in the study. Two controllers were randomly assigned to each display panel–emergency condition combination. The time (in seconds) required to stabilize the emergency condition was recorded. The resulting data and analysis results are given below. Display panel data Emergency condition Display panel 1 2 3 4 A 17 25 31...
Using the following data set, conduct an independent samples t-test. Use a= 0.05 and a two-tailed test. Sample 1: 14, 14, 13, 13, 10, 12, 14, 15, 17 Sample 2: 15, 11, 15, 13, 14, 13, 14, 14, 15 1. hypotheses: null and alternative 2. t-critical value; shade of regions of rejection 3. t-obtain 4. conclusion 5. decide if significant 6. compute for confidence interval is significant
(a) Draw a curve and label each part to reflect a left, right, or two-tailed test (b) Claim: Show in symbols H0, Ha (c) Critical value- find the z0 or t0 values (d) What are the standardized test statistic z or t, and the P values from the calculator? (e) Comparing the critical values, α value, against the calculator results, state whether you reject, or fail to reject the null hypothesis (f) Interpret the decision in the context of the...
Do a two-sample test for equality of means assuming unequal variances. Calculate the p-value using Excel. (a-1) Comparison of GPA for randomly chosen college juniors and seniors: x⎯⎯1x1 = 4.75, s1 = .20, n1 = 15, x⎯⎯2x2 = 5.18, s2 = .30, n2 = 15, α = .025, left-tailed test. (Negative values should be indicated by a minus sign. Round down your d.f. answer to the nearest whole number and other answers to 4 decimal places. Do not use "quick"...
