What type of data is commonly analyzed using a chi-square test?*1 pointContinouous dataRatio dataOrdinal dataNominal or categorical data

Chi-squared can be used to understand the relationship betweenGroup of answer choicesany two variables.one categorical and one continuous variable.two continuous variables.two categorical variables.

A necessary assumption that is made when conducting a chi-squared analysis is: (select the one false statement)Group of answer choicesat least 80% of the observed frequencies are greater than or equal to 5all expected frequencies are greater than or equal to 1the sample size is large enough to approximate a Binomial random variable by a normal random variablethe sample data consist of frequency counts for different categories of a tablea subject can only fit into one category of the table (i.e. they belong with only one cell of the table)

We shouldn't explore data unless we have a hypothesis to test. Group of answer choicesTrueFalse

A table classifying a random sample of students by course and whether or not they are "binge drinkers" is given below.Science (BSc, BBiomed, BEng) Arts (BA, BMusic) Total"binge drinker" 68 63 131not "binge drinker" 355 423 778Total 423 486 909When testing the null hypothesis that there is no association between gender and "binge drinking",  which ONE of the following statements is FALSE?Group of answer choicesThe assumptions for the chi-squared test are invalid.A suitable test statistic has a value of 1.33A suitable test statistic has a value of 1.776The p-value for the test is 0.183Based on this data, there is insufficient evidence to suggest that science students are more likely than arts students to be "binge drinkers".
