You can find the critical values for an ANOVA hypothesis using the F-table. Because the F-distribution is based on two types of degrees of freedom, there’s one table for each possible value of alpha (the level of significance).
Numerator degrees of freedom = treatments – 1 = t – 1 = 3 – 1 = 2
Denominator degrees of freedom = total observations minus treatments = N – t = 3*6– 3 = 15
From the F Table,
student is using ANOVA to test 3 samples of data. Each sample has 6 data values....
student gathers student final exam scores for 3 different professors teaching the same class. She uses ANOVA to est the claim that the 3 sections have the same average score. Her p-value is very close to 0. What conclusion should she draw? Select one: O a. The test is not significant and it appears that the 3 samples have the same final exam averages O b. The test is significant and it appears that the 3 samples have the same...

The degrees of freedom for the critical value of Fare a. 7 numerator and 20 denominator degrees of freedom O b. 5 numerator and 114 denominator degrees of freedom O c. 6 numerator and 133 denominator degrees of freedom d. 6 numerator and 20 denominator degrees of freedom
A student uses ANOVA to test the claim that 4 random samples of IQ scores from 3rd grade students in New York. Texas, California, and Maryland have the same mean. He ends up rejecting Ho. Based solely on the ANOVA, what is a possible true statement? Select one: O a. Students from the 4 states have different average IQ scores O b. The average 1Q scores from New York are different than those from Texas. C. The average iQ scores...
please show all 6 steps with calculations! Assignment # 1 3: Between-Subjects ANOVA Instructions: For each research scenario, please complete the source table and conduct a hypothesis test at a-05 significance level using a between-groups ANOVA to determine if one group is different from the others. Please be sure to show your work when performing mathematical operations. Please round all calculations to two decimal places. Scenario 1. Dr. Smith has developed a new way to administer a GRE prep workshop...
please answer these for me. a dependent samples -test a one-way ANOVA a stay of conversation topic and references to oneself in conversation, subjects in two groups are their scores oi a self-monitoring scale. Subjects in Group A engage in conversation with a who taiks about a neutral topic, and those in Group B converse with a confederate who talks h a or d hitched by rsonal topic. The hypothesis is that the personal topic will encourage more references to...
Conduct an independent samples One Way ANOVA using the following data: 1. A researcher is also a fan of mixed martial arts (MMA) and helps run an MMA gym in his spare time. He decides to see which striking style is most effective and trains his fighters in one of three styles, then records the amount of significant strikes the fighters land in their next fights. The data is as shown: Muay Thai style Taekwondo style Boxing style 16 11...
Alejandra is using a one-sample ?‑test to test the null hypothesis ?0:?=10.0 against the alternative ?1:?<10.0 using a simple random sample of size ?=15. She requires her results to be statistically significant at level ?=0.05. Determine the maximum value of ?t that will reject this null hypothesis. You may find this table of ?t‑critical values useful. If you are using software, you may find this catalog of software guides useful. Give your answer to three decimal places. ?=
