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

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
