FALSE.
The degrees of freedom will be k-1 and not n-1. In a chi square distribution we identify the claim by stating the null and alternative hypothesis. After specifying the level of significance we identify the degrees of freedom (d.f.)

Assuming an experiment has k categories, the goodness-of-fit test statistic is assumed to follow a normal distribution with (k-1) degrees of freedom. True False Question 6 1 pts The Boston public school district has had difficulty maintaining on-time bus service for its students. Suppose the district develops a new bus schedule to help combat chronic lateness on a particularly woeful route. Historically, the bus service on the route has been, on average, 10 minutes late. After the schedule adjustment, the...
11.2 You intend to conduct a goodness-of-fit test for a multinomial distribution with 7 categories. You collect data from 74 subjects. What are the degrees of freedom for the x2 distribution for this test? d.f. = Submit License Question 1. Points possible: 1 Unlimited attempts. You are conducting a multinomial Chi-Square Goodness of Fit hypothesis test for the claim that the 4 categories occur with the following frequencies: Ho:PA = 0.2; PB = 0.3; pc = 0.3; PD = 0.2...
The test statistic for goodness of fit has a chi-square distribution with k - 1 degrees of freedom provided that the expected frequencies for all categories are a. 10 or more. b. k or more. c. 2k. d. 5 or more.
You intend to conduct a goodness-of-fit test for a multinomial distribution with 4 categories. You collect data from 63 subjects. What are the degrees of freedom for the χ 2 distribution for this test?
You intend to conduct a goodness-of-fit test for a multinomial distribution with 4 categories. You collect data from 87 subjects. What are the degrees of freedom for the χ2χ2 distribution for this test? d.f. =
You intend to conduct a goodness-of-fit test for a multinomial distribution with 6 categories. You collect data from 83 s What are the degrees of freedom for the x distribution for this test? ubjects This is attempt 1 of 3. cBook A
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...
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
a) true b) false 42. For a chi-square distributed random variable with 10 degrees of freedom and a level of sigpificanoe computed value of the test statistics is 16.857. This will lead us to reject the null hypothesis. a) true b) false 43. A chi-square goodness-of-fit test is always conducted as: a. a lower-tail test b. an upper-tail test d. either a lower tail or upper tail test e. a two-tail test 44. A left-tailed area in the chi-square distribution...
