Class Parameters vs. Personal Sample Data The results from the data collection from all last year's stat classes from Part 1 of the Project is below. Your statistics from Part 1 needs to be used as sample data for all the Steps of Part 2. The parameters below will be used in Step 2,3 & 4 along with yours. Population Mean
\mu =19.6(minutes) Pop. Standard Deviation
\sigma =10.5(minutes) (Assume
n>30.) Your Sample Mean
\bar{x} =20.3 Your Sample Standard Deviation

95%confidence interval for the population's mean study time.
q,
<\mu <
q,or (
q,, _) B. If someone were to ask you what this particular confidence interval means, what would you say? STEP 4: Hypothesis Test Test the hypothesis that the population's mean is different from the sample's mean value. Use
\alpha =0.05. Alternative hypothesis
(H_(1)):
q,Null hypothesis
(H_(0))P-value
◻Test statistic:
◻Conclusion: Do you reject the null hypothesis (yes or no)?
◻If someone were to ask what the conclusion means in this particular study, what would you say?
