Are freshmen psychology majors more likely to change their major before they graduate compared to freshmen business majors? 327 of the 605 freshmen psychology majors from a recent study changed their major before they graduated and 326 of the 682 freshmen business majors changed their major before they graduated. What can be concluded at the a = 0.01 level of significance? For this study, we should use Select an answer a. The null and alternativ Select an answer t-test for the difference between two dependent population means Ho: Select an answer z-test for a population proportion H1: Select an answer V t-test for a population mean b. The test statistic ? v c. The p-value = d. The p-value is ?V a z-test for the difference between two population proportions e. Based on this, we shoul t-test for the difference between two independent population means f. Thus, the final conclusil. O The results are statistically significant at a = 0.01, so there is sufficient evidence to conclude that the proportion of the 605 freshmen psychology majors who changed their major is greater than the proportion of the 682 freshmen business majors who change their major. O The results are statistically significant at a = 0.01, so there is sufficient evidence to conclude that the population proportion of freshmen psychology majors who change their major is greater than the population proportion of freshmen business majors who change their major. O The results are statistically insignificant at a = 0.01, so there is insufficient evidence to conclude that the population proportion of freshmen psychology majors who change their major is greater than the population proportion of freshmen business majors who change their major.
