1.Sap software company is conduction a two-tailed test of means but the new developmental software program only calculates a one-tailed p-value equal to 0.19. the actual p-value for your test is:
2.One-way anova uses a one-tail hypothesis while two-way anova uses a two-tail hypothesis test.
Ture or False
1. Actual p - value = 2*0.19 = 0.38
Option C is correct.
2. This statement is False because both uses one tail hypothesis.

A) A one-way ANOVA test: is a left-tailed test is a right-tailed test is a two-tailed test Can be either a right-tailed or a left-tailed test 1.B) The p-value of the ANOVA F test is a. Area below (left) the value of the test statistic of the corresponding F distribution b. Area above (right) the value of the test statistic of the corresponding F distribution c. Half of the area above (right) the value of the test statistic of the corresponding...
Question 2In one tailed T-test, if the test statistics is \(\mathrm{t}\) and \(\mathrm{t}_{0}\) is the t-value under null hypothesis, then \(\mathrm{p}\) -value \(=\operatorname{Pr}\left(\mathrm{t}<\mathrm{t}_{0} \mid\right.\) null hypothesis is true) if \(\mathrm{t}_{0}>0\) and p-value \(=\operatorname{Pr}\left(t>t_{0} \mid\right.\) null hypothesis is true) if \(t_{0}<0\).Question 3In a recent twin study from researchers at King's College London, the researchers wanted to first test whether identical twins show statistically significantly different thigh muscular power. To test this, they recruited 20 identical female twins. For this analysis,one-way ANOVA...
12. (a) A two-tailed test of a one-sample hypothesis of a mean yields a test statistic of z= 1.47. What's the p-value? (b) A one-tailed test of a two-sample hypothesis involving the difference of sample means yields t= 1.85, with 12 degrees of freedom. What is the p-value?
The null and alternative hypotheses for a hypothesis test of the difference in two population means are: Null Hypothesis: Alternative Hypothesis: Notice that the alternative hypothesis is a one-tailed test. Suppose ttest_ind method from scipy module is used to perform the test and the output is (3.25, 0.0043). What is the P-value for this hypothesis test? Select one. Question 2 options: 3.25 -3.25 0.0043 0.00215
The null and alternative hypotheses for a hypothesis test of the difference in two population means are: Null Hypothesis: Alternative Hypothesis: Notice that the alternative hypothesis is a two-tailed test. Suppose ttest_ind method from scipy module is used to perform the test and the output is (-1.99, 0.0512). What is the P-value for this hypothesis test? Select one. Question 4 options: 0.0512 1.99 0.0256 -1.99
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...
1:When performing a two-tailed test for the difference between means, with Ho:-=0, the hypothesized difference between the two population means is zero. Select one: True False Question 2: If the null hypothesis is - 10 and the alternative hypothesis is - > 10, the appropriate test to use is a lower tail test. Select one: True False Question 3:Suppose it desired to compare two physical education training programs for preadolescent girls. A total of 82 girls are randomely selected, with...
Easier Professor - Significance Test (Raw Data, Software Required): Next term, there are two sections of STAT 260 - Research Methods being offered. One is taught by Professor Smith and the other by Professor Jones. Last term, the class average from Professor Smith's section was higher. You want to test whether or not this difference is significant. A significant difference is one that is not likely to be a result of random variation. The scores from last year's classes are...
Ste?1 (a) Find an interval containing the ponding P-value for a two-tailed test. we are given a Student's t distribution with df. # 9 and t-, 1.890. We wish to find an interval containing the corresponding P-value for a two-tailed test. To do this, we will use the Critical values for Student'st Distribution. Below is an excerpt from this table. one-tail area 0.250 0.125 0.100 0.075 0.050 0.025 0.010 0.005 0.0005 two-tail areal o.500 ?.250 o.200 0.150 0.100 0.050 0.020...
10) In a left-tailed test comparing two means with unknown variances assumed to be equal, the test statistic was t = -1.81 with sample sizes of n1 = 8 and n2 = 12. The p-value would be: Select one: a. between .025 and .05 b.between .01 and .025 c.between .05 and .10 d. Must know α to answer The owner of a fish market determined that the weights of catfish are normally distributed, with a mean of 3.2 pounds and...
