- A researcher is studying whether average GPA is dependent on whether the students are in a 2-year college, public university, or private university. The researcher should use a 1-way ANOVA for this study. True or falseA major credit card company is investigating whether the distribution of the number of credit cards used by its customers has changed from last year to this year. Customers are classified as using 1 card, 2 cards, or more than 2 cards. The company conducts a chi-square goodness-of-fit test to investigate whether there is a change in the distribution of number of cards used from last year to this year. The value of the chi-square test statistic was χ2=7.82 with a corresponding p-value of 0.02. Assuming the conditions for inference were met, which of the following is the correct interpretation of this p-value? There is a 2 percent chance that the company’s claim is correct. A There is a 2 percent chance of obtaining a chi-square value of at least 7.82. B If the null hypothesis were true, there is a 2 percent chance of obtaining a chi-square value of at least 7.82. C If the null hypothesis were true, there is a 2 percent chance that the company’s claim is…A researcher reports an F-ratio with dfbetween=2 and dfwithin=30 for an independent-measures ANOVA.
