poll of 946 college students revealed that 30.2% of them work a full-time job. At the .03 level of significance, test the claim that less than 33% of college students work full-time. Find the claim, Null Hypothesis (H0), and Alternative Hypothesis (H1).                                    Find the critical value.                                      Find the test statistic.                                    Find the p-value.                                 Do you reject or fail to reject the null hypothesis?                                      State your conclusion. -Is there sufficient evidence or not?
