a …… table has data arranged for the chi square independence test a) chi square b)...
When we carry out a chi-square test of independence, the chi-square statistic is based on (rxc)-1 degrees of freedom, where r and c denote, respectively, the number of rows and columns in the contingency table. True or false
What is the idea behind the chi-square test for independence? Select one: a. to compare the quantile-quantile (Q-Q) plot with what would be expected under independence b. to compare the actual counts in a contingency table with what would be expected under independence c. to compare the cumulative distribution with what would be expected under independence d. none of these choices
You observe 100 randomly selected college students to find out whether they arrive on time or late for their classes. The table below gives a two-way classification for these students.GenderOn TimeLateFemale359Male4313For a chi-square test of independence for this contingency table, what is the number of degrees of freedom?
this is the table given Perform a chi-square independence test using the critical value approach, provided the conditions for using the test are met. Be sure to state the hypotheses and the significance level, to obtain the expected frequencies, to obtain the critical value, to compute the value of the test statistic, and to state your conclusion. 160 students who were majoring in either math or English were asked a test question, and the researcher recorded whether they answered the...
The null hypothesis for a chi-square contingency test of independence for two variables always assumes that the variables are independent.AnswerTrueFalse
Does the data meet the conditions for the chi-square test? StatCrunch Instructions: Test of Independence Using Technology Next we will use StatCrunch to calculate the expected counts: Enter Yes and No in column var1. Enter the observed counts as they appear in the table above (not including the totals) into columns var2 and var3. Rename: var1 as "911", var2 as "No Risk" and var3 as "M to S Risk" Choose Stat -> Tables -> Contingency -> with summary Select the...

10.00 points When we carry out a chi-square test of independence, the alternate hypothesis states that the two relevant classifications O are mutually exclusive. O form a contingency table with rrows and c columns O have (1 - 1)(C-1) degrees of freedom are statistically dependent O O are normally distributed
Perform a chi-square independence test using the critical value approach, provided the conditions for using the test are met. Be sure to state the hypotheses and the significance level, to obtain the expected frequencies, to obtain the critical value, to compute the value of the test statistic, and to state your conclusion. 160 students who were majoring in either math or English were asked a test question, and the researcher recorded whether they answered the question correctly.
