in a survey of 5000 students taking SAT 350 were undecided on an intended college major. At a=0.10 can we reject the claim that the proportion of students taking the SAT who are undecided on an intended major has not changed? Identify the Ho and H1. then determine whether to use z or t test. then find the critical value and identify the rejected region. then find the appropriate standardized test statistic. then decide whether to reject or fail to reject the null hypothesis
