1. A professor is interested in the number of hours/week students study for a statistics class. In the past, he found that students study an average of 7 hours each week. He selects a sample of 6 students from his current class and asks them how much they study each week. Below you will find the data: 4, 5, 3, 2, 2, 8

By hand, conduct a single sample t-test to determine if the current students’ mean number of hours spent studying differs from the mean of 7 found in the past. Hint: Follow the 4 steps of hypothesis testing and notate them below.

M:_________, SD:_________, sM:_________, df:_________, tobs:_________, tcrit:_________ Reject or fail to reject the Null Hypothesis: _______

Using APA style, please write out the results. Report whether p is above or below the alpha level (you do not have the exact p-value). A successful APA statement will include the hypothesis test used, the mean and standard deviation of the sample, the mean of the population, a statement of significance, and a statement of inferential statistics. Round all values to two decimal places.  

2. An Industrial-Organizational Psychologist is seeing how often employees check their phone in an hour at a specific workplace, suspicious that his employees check their phone much more often than employees in the past. He has found that employees of a similar job position from two years prior checked their phone an average of 6 times an hour. He selects a sample of 7 employees and sees how often they check their phone in an hour. The data can be found below: 6, 8, 4, 6, 5, 7, 5

By hand, conduct a single sample t-test to determine if the number of times the current employees check their phone is larger than the mean of 6 found in the past.

M:_________, SD:_________, sM:_________, df:_________, tobs:_________, tcrit:_________ Reject or fail to reject the Null Hypothesis: _______

Using APA style, please write out the results. Report whether p is above or below the alpha level (you do not have the exact p-value). A successful APA statement will include the hypothesis test used, the mean and standard deviation of the sample, the mean of the population, a statement of significance, and a statement of inferential statistics. Round all values to two decimal places.
