The test statistic ? v = (please show your answer to 3 decimal places. ) c. The p-value = (Please show your answer to 4 decimal places.) d. The p-value is ? v o e. Based on this, we should Select an answer | the null hypothesis. f. Thus, the final conclusion is that ... The results are statistically insignificant at a = 0.05, so there is statistically significant evidence to conclude that the population proportion of freshmen psychology majors who change their major is the same as the population proportion of freshmen business majors who change their major. O The results are statistically insignificant at a = 0.05, so there is insufficient evidence to conclude that the population proportion of freshmen psychology majors who change their major is less than the population proportion of freshmen business majors who change their major. The results are statistically significant at a = 0.05, so there is sufficient evidence to conclude that the proportion of the 628 freshmen psychology majors who changed their major is less than the proportion of the 710 frochm
