Question

A random number generator was used to choose one hundred students from the freshman and sophomore classes of a mid-sized university to participate in a study designed to increase student interest in pursuing intemships and research opportunities at this university before their junior year. Using an alphabetical list of last names from the sample, the first 50 students were assigned to attend weekly hour-long meetings during which counselors from the university's career center would discuss with them opportunities for employment and graduate school options. The remaining 50 students also attended weekly hour-long meetings during which various campus issues were discussed, but there were no graduate school or career options. At the end of the fall semester, the Consideration of Future Consequences (CFC) scale was administered to the students in both groups

Explanation / Answer

Answer to question# 8)

The control group is the group with which only campus issues were discussed

And the experimental group is the group with which only employment opportunities and graduate school options were discussed

.

Answer to question#9)

The appropriate set of hypothesis are as follows:

Null hypothesis: CFC score for both the groups is same

Alternate hypothesis: The CFC score for both the groups is different

.

Answer to question#10)

If they both are equal this implies null hypothesis is true, and error would have occur only when you reject the null hypothesis. This type of error is called Type I error

.

Answer to question#11)

Type I error is when the two groups have same score but we end up rejecting the null hypothesis

.

Answer to question #12)

Type II error will occur when in fact the two groups have different average scores but after conducting the test we decide to fail to reject the null.

.

Answer to question# 13)

We end up conducting type I error in this scenario
