A researcher wants to know if students who do not plan to apply for financial aid have more variability on the SAT math test than those who do. Random samples of 25 students who do not plan to apply for aid (sample 1) as well as 30 who do (sample 2) are summarized below:

​

Do not plan to apply for aidDo plan to apply for aid
n= 21n= 16
s= 123.1s= 119.4

​

Does it appear that students who do not plan to apply for financial aid are less consistent on the SAT math test than those who do plan to apply for aid? Select the appropriate critical value (CV), test statistic (TS), and decision and state the alternative hypothesis. (Useα= 0.01).


◦

CV = 3.37; TS = 1.0310; fail to rejectH0; \(\style{font-family:Times New Roman;}{H_1}\)states that students who do not apply for aid have scores that vary just as much as those who do apply for aid.


◦

CV = 3.37; TS = 1.0629; fail to rejectH0;\(\style{font-family:Times New Roman;}{H_1}\)states that students who do not apply for aid have more variable scores than those who do apply for aid.


◦

CV = 0.2967; TS = 1.0310; rejectH0; \(\style{font-family:Times New Roman;}{H_1}\)states that students who do not apply for aid have scores that vary just as much as those who do apply for aid.


◦

CV = –3.26; TS = –1.0154; rejectH0;\(\style{font-family:Times New Roman;}{H_1}\)states that students who do not apply for aid have scores that vary just as much as those who do apply for aid.

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.
