not rejecting the null hypothesis means that the assigned value under the null is the true population value. true or false
True
Because not rejecting means accepting the null hypothesis , we accept the null then we accept under null hypothesis decision.
not rejecting the null hypothesis means that the assigned value under the null is the true...
rejecting the null hypothesis does not imply that the hypothesized value is the wrong assumption the population value. true or false
The larger the p-value, the higher the chance of rejecting the null hypothesis. O True O False
In hypothesis testing, which of the following results in a type I error? Rejecting a true null hypothesis Rejecting a true alternative hypothesis Rejecting a false null hypothesis Rejecting a false alternative hypothesis
True or false The practical significance of a decision rejecting the null hypothesis should always be considered with every statistical test outcome.
Explain what a P-value is. What is the criterion for rejecting the null hypothesis using the P-value approach? Explain what a P-value is. Choose the correct answer below. OA. A P-value is the probability of observing a sample statistic as extreme or more extreme than the one observed under the assumption that the statement in the null hypothesis is true B. A P-value is the number of standard deviations that the observed proportion is from the proportion stated in the...
a is .05 and N-25, the probability of rejecting the null hypothesis if the mull hypothesis is true is: a. .os b..95 c. 05/25 - 01 d..95/25 = .19 e. insufficient information to answer as the popu 4. The sampling distribution of the mean always has the same distribution of the raw scores. a. mean b. standard deviation c. skew d. a and b e. all of the above S. If the sample size on which a standard deviation is...
13) Determine the decision criterion for rejecting the null hypothesis in the given hypothesis test; i.e., describe the values of the test statistic that would result in rejection of the null hypothesis. Suppose you wish to test the claim that μd, the mean value of the differences d for a population of paired data, is greater than 0. Given a sample of n = 15 and a significance level of α = 0.01, what criterion would be used for rejecting...
The practical significance of a decision rejecting the null hypothesis should always be considered with every statistical test outcome. A. TRUE B. FALSE
Question 1: True or False (2 points each) a) ANOVA tests the null hypothesis that the sample means are all equal. b) A strong case for causation is made in an observational study. c) In rejecting the null-hypothesis, one can conclude that all the means are different from each other d) One-way ANOVA can be used only when there are fewer than five means to be compared. e) The null hypothesis for the Levene’s test for homogeneity of variance is...
The higher the alpha level, a. the lower the probability of rejecting the null hypothesis. b. the greater the probability of rejecting the null hypothesis. c. the larger the sample size has to be to reject the null hypothesis. d. the more desirable the two-tailed test. When solving the formula for finding Z(obtained) with sample proportions in the two-sample case, we must first estimate a. the population proportion. b. the critical region. c. the ratio of the sample proportions. d....
