Record your pulse rate (per minute) at two different times during the day, once in the morning (ideally upon waking up), and then at the end of the day (ideally before going to bed).
Morning pulse rate is....Evening pulserate is....
Morning 70, 68, 80, 72
Evening 76 ,68, 66, 74
(a)Using Minitab, create two 90% confidence intervals for the mean pulse rate. One for the morning sample and one for the evening sample.Include in your post:
- Your confidence intervals.
- Do these intervalss overlap?
- What information can or cannot be determined if the intervals overlapped or didn't overlap?
(b) Conduct a hypothesis test to test the claim that the meanmorningpulse rate is 60 bpm. Include the following in your post.
- Give the null and alternative hypotheses.
- What are the t- and p-values
- According to the p-value, should you reject or not reject the null hypothesis if you use a 0.05 significance level?
- Give a complete sentence that restated the hypothesis and your conclusion, including the p-value and the significance level.
- What is the probability of a Type I error for this test and explain what a Type I error would be in the context of this test.
(c)What possible key considerations should we take into account as we interpret the result of the hypothesis test in regards to the pulse rate data that was collected?
