Need help to solve this question from chapter 8.3 of Triola statistics. Show steps and formulas to solve and explanation using TI-84 calculator.
-> A group of students estimated the length of one minute without reference to a watch orclock, and the times(seconds) are listed below. Use a 0.10 significance level to test the claim that these times are from a population with a mean equal to 60 seconds. Does it appear that students are reasonably good at estimating oneminute?
67 | 80 | 38 | 66 | 40 | 27 | 59 | 65 | 68 | 48 | 64 | 68 | 92 | 92 |
- Assuming all conditions for conducting a hypothesis test aremet, what are the null and alternativehypotheses?
H0: =60 seconds
H1: 60 seconds
- Determine the test statistic.
(Round to two decimal places asneeded.)
- Determine theP-value.
(Round to three decimal places asneeded.)
- State the final conclusion that addresses the original claim.
