What can be concluded at the αα = 0.05 level of significance?

For this study, we should use: Select an answer. z-test for a population mean or t-test for a population mean ?
The null and alternative hypotheses would be:

H0:H0: ? p or μ Select an answer < ≠ ≤ > = ≥

H1:H1: ? μ or p Select an answer = < ≠ ≥ ≤ >

The test statistic ? z or t ? = _______ (please show your answer to 3 decimal places.)
The p-value = ______ (Please show your answer to 4 decimal places.)
The p-value is ? > or ≤
Based on this, we should? Select an answer. accept? fail to reject? or reject ? the null hypothesis.
Thus, the final conclusion is that ...
- The data suggest the populaton mean is significantly more than 2 at αα = 0.05, so there is enough evidence to conclude that the population mean study time per unit for statistics students is more than 2.
- The data suggest the population mean is not significantly more than 2 at αα = 0.05, so there is enough evidence to conclude that the population mean study time per unit for statistics students is equal to 2.
- The data suggest that the population mean study time per unit for statistics students is not significantly more than 2 at αα = 0.05, so there is not enough evidence to conclude that the population mean study time per unit for statistics students is more than 2.
Interpret the p-value in the context of the study.
- There is a 25.93189482% chance of a Type I error.
- If the population mean study time per unit for statistics students is 2 and if you survey another 12 statistics students then there would be a 25.93189482% chance that the sample mean for these 12 statistics students would be greater than 2.22.
- If the population mean study time per unit for statistics students is 2 and if you survey another 12 statistics students then there would be a 25.93189482% chance that the population mean study time per unit for statistics students would be greater than 2.
- There is a 25.93189482% chance that the population mean study time per unit for statistics students is greater than 2.
