A researcher conducts a hypothesis test using a sample from an unknown population. If the t statistic has df = 35, how many individuals were in the sample?
A) n = 34
B) n = 35
C) n = 36
D) n=32
Question 2A chi-square test for goodness of fit is used to examine the distribution of individuals across four categories, and a chi-square test for independence is used to examine the distribution of individuals across six categories in a 2 X 3 matrix of categories. Which test has the larger value for df?
A) The goodness of fit has the larger value.
B) The test for independence has the larger value.
C) Both tests have the same df value.
D) The df value depends on the sizes of the samples that are used.
Question 3When n is small (less than 30), how does the shape of the t distribution compare to the normal distribution?
A) It is almost perfectly normal.
B) It is flatter and more spread out than the normal distribution.
C) It is taller and narrower than the normal distribution.
D) There is no consistent relationship between the t distribution and the normal distribution.
Question 4A 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 X 2 matrix of categories. Which test has the larger value for df?
