Question 1

Formulate the null and alternative hypotheses for a hypothesis test.

In 1990,  the average math SAT score for students at one school was 498. Five years later, a teacher wants to perform a hypothesis test to determine whether the average math SAT score of students at the school has changed from the 1990 mean of 498.
◦ H0:: μ ≥ 498
Ha: μ < 498
◦ H0: μ = 498
Ha: μ < 498
◦ H0: μ = 498
Ha: μ ≠ 498
◦ H0: μ = 498
Ha: μ > 498

Question 2

Formulate the null and alternative hypotheses for a hypothesis test.

A consumer advocacy group claims that the mean amount of juice in a 18 ounce bottled drink is not
as stated by the bottler.
◦ H0:  μ = 18 ounces
Ha:  μ > 18 ounces
◦ H0:  μ = 18 ounces
Ha:  μ ≠ 18 ounces
◦ H0:  μ ≠ 18 ounces
Ha:  μ = 18 ounces
◦ H0:  μ = 18 ounces
Ha:  μ < 18 ounces

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.
