The chi-square goodness-of-fit is _________ a one-tailed test with the rejection region in the right tail. always sometimes never
solution:- always
The chi-square goodness-of-fit is always a one-tailed test with the rejection region in the right tail
The chi-square goodness-of-fit is _________ a one-tailed test with the rejection region in the right tail....
When using a chi-square goodness-of-fit test with multinomial probabilities, the rejection of the null hypothesis indicates that at least one of the multinomial probabilities is not equal to the value stated in the null hypothesis. O True False
In a one-tailed test, the rejection region is located under one tail (left or right) of the corresponding probability distribution, while in a two-tailed test this region is located under both tails. True False Question 8 1 pts The owner of a large car dealership believes that the financial crisis decreased the number of customers visiting her dealership. The dealership has historically had 800 customers per day. The owner takes a sample of 100 days and finds the average number...
A one-tailed test is a a. hypothesis test in which rejection region is only in the upper tail of the sampling distribution b. hypothesis test in which rejection region is in both tails of the sampling distribution c. hypothesis test in which rejection region is only in the lower tail of the sampling distribution d. hypothesis test in which rejection region is in one tail of the sampling distribution
Find the critical value(s) and rejection region(s) for a two-tailed chi-square test with a sample size n equals 20 and level of significance alphaαequals=0.05 please show the graph as well
Which of the statements are correct? A condition for using the chi-square goodness-of-fit test is that all expected counts must be at least two. A condition for using the chi-square goodness-of-fit test is the observations are based on a random sample. The chi-square goodness-of-fit test uses n − 5 degrees of freedom. A) I only B) II only C) I and II only D) II and III only E) I, II, and III

A chi-square test for goodness of fit is used to examine the distribution of individuals across three categories, and a chi-square test for independence is used to examine the distribution of individuals in a 2×3 matrix of categories. Which test has the larger value for df? a. The test for independence b. Both tests have the same df . c. The df value depends on the sizes of the samples that are used. d. The test for goodness of fit
Assume that a Chi-square test was conducted to test the goodness of fit to a 3:1 ratio and that a Chi-square value of 2.62 was obtained (Table value is equal to 3.84). Should the null hypothesis be accepted? How many degrees of freedom would be associated with this test of significance?
The chi-square goodness of fit test can be used when: Select one: a. We conduct a multinomial experiment. b. We perform a hypothesis test to determine if a population has a normal distribution. c. We perform a hypothesis test to determine if two population variances significantly differ from each other. d. We conduct a binomial experiment. The x statistic from a contingency table with 6 rows and five columns will have Select one: a. 24 degrees of freedom b. 50...
