Previously, 3% of mothers smoked more than 21 cigarettes during their pregnancy. An obstetrician believes that the percentage of mothers who smoke 21 cigarettes or more is less than 3% today. She randomly selects 150 pregnant mothersand finds that 3 of them smoked 21 or more cigarettes during pregnancy. Test the researcher's statement at the a = 0.05 level of significance.What are the null and alternative hypotheses?= 0.03 versus H,: pHo: P(Type integers or decimals. Do not round.)0.03Because npo (1- Po) = || V 10, the normal model(Round to one decimal place as needed.)V be used to approximate the P-value.

Solution-: Given: x=3,n=150,P0=0.03,α=0.05 What is null and alternative hypothesis?

Answered: Previously, 3% of mothers smoked more…

Are freshmen psychology majors just as likely to change their major before they graduate compared to freshmen business majors? 366 of the 673 freshmen psychology majors from a recent study changed their major before they graduated and 394 of the 705 freshmen business majors changed their major before they graduated. What can be concluded at the a = 0.10 level of significance? For this study, we should use z-test for the difference between two population proportions a. The null and alternative hypotheses would be: Ho: p1 p2 v (please enter a decimal) H1: p1 p2 (Please enter a decimal) b. The test statistic z v -0.508 X (please show your answer to 3 decimal places.) c. The p-value = 0.6115 X (Please show your answer to 4 decimal places.) d. The p-value is > vV a e. Based on this, we should fail to reject the null hypothesis. f. Thus, the final conclusion is that ... O The results are statistically significant at a = 0.10, so there is sufficient evidence to conclude that the proportion of…
