The College Board states that the average math SAT score is 514 with a standard deviation of 117. Colleen gathered data from 50 students in her graduating class and found the average score to be 523. She thinks that her class’s math SAT score is different from the average. Which of the following are the correct null hypothesis and alternate hypothesis? H0: Mu = 514; Ha: Mu greater-than 514 H0: Mu not-equals 514; Ha: Mu = 523 H0: Mu = 514; Ha: Mu not-equals 514 H0: Mu = 514; Ha: Mu = 523.

Respuesta :

From the hypothesis test, we have that:

  • The null hypothesis is [tex]H_0: \mu = 514[/tex].
  • The alternative hypothesis is: [tex]H_1: \mu \neq 514[/tex]

At the null hypothesis, it is tested if her average is the same as the national of 514, hence:

[tex]H_0: \mu = 514[/tex]

At the alternative hypothesis, it is tested if it is different, hence:

[tex]H_1: \mu \neq 514[/tex]
