The population mean on a standardized math test is 75. A tutoring program is implemented at a local college to determine if the math scores would improve as a result. A one-sample t test is conducted. What is the alternative hypothesis?
A) H₁: μ ≥ 75
B) H₁: μ ≠ 75
C) H₁: μ 75
D) H₀: μ = 75

Question

The population mean on a standardized math test is 75. A tutoring program is implemented at a local college to determine if the math scores would improve as a result. A one-sample t test is conducted. What is the alternative hypothesis?
A) H₁: μ ≥ 75
B) H₁: μ ≠ 75
C) H₁: μ > 75
D) H₀: μ = 75

Quizplus · Accepted Answer

The alternative hypothesis (H₁) should state the possibility of an improvement in math scores, which would mean a higher population mean. Therefore, H₁: μ > 75 is the best choice.
