A university is interested in promoting graduates of its honors program by establishing that the mean GPA of these graduates exceeds 3.50. A sample of 36 honors students is taken and is found to have a mean GPA equal to 3.60. The population standard deviation is assumed to equal 0.40. The parameter to be tested is . Multiple Choice the mean GPA of all university students the mean GPA of the university honors students the mean GPA of 3.60 for the 36 selected honors students

The parameter to be tested is the mean GPA of the university honors students.

Step-by-step explanation:

A hypothesis test can be performed to determine how to promote graduates to the honors program according to the GPAs of the students.

The procedure applied is, students having a GPA of more than 3.50 will be promoted to the honors program.

The GPA of 3.50 is the mean GPA of all the graduate students at the university.

To test whether the procedure is correct or not a sample of 36 honors students is taken and is found to have a mean GPA equal to 3.60.

In this case the hypothesis test will be performed to test whether the mean GPA of the honors students is less than 3.50.

The hypothesis is:

H₀: The mean GPA of the honors students is not less than 3.50, i.e. μ ≥ 3.50.

Hₐ: The mean GPA of the honors students is less than 3.50, i.e. μ < 3.50.

Thus, the parameter to be tested is the mean GPA of the university honors students.
