Question

A university is interested in promoting graduates of its honors program by establishing that the mean GPA of these graduates exceeds 4.3. A sample of 44 honors students is taken and is found to have a mean GPA equal to 4.4. The population standard deviation is assumed to equal 0.40. The parameter to be tested is that students who study harder make better grades. True False Question 22 1 pts The alternative hypothesis typically agrees with the status quo. O True False

Answer 1

1. False

In this scenario, through the result it is established that the mean GPA of graduate students who have taken up honors program is 4.4, i.e. more than the mean GPA of 4.3 required. This establishes the fact that the students who enroll for honors program have higher GPA than the students who do not enroll for honors program, which also establishes that the students who enroll for honors program are more intelligent than other students.

2. True

The alternative hypothesis in this scenario typically agrees with the status quo that the students who do not study harder do not make better grades. This is proven through the results carried out as well.
