Pulse Rates. One of the authors claimed that his pulse rate was lower than the mean pul se rate of statistics students. The author's pulse rate was measured and found to be 60 beats per minute, and the 20 students in his class measured their pulse rates. The 20 students had a mean pulse rate of 74.5 beats per minute, and their standard deviation was 10.0 beats per minute. ls there sufficient evidence to support the claim that the mean pul se rate of statistics students is greater than 60 beats per minute ? Use a 0.05 significance level.

• Show how t tests can be used to analyze real-life data. Think about how you might answer each of the questions.
• Think about one small data set that you would like to compare to a proposed mean. For example, you could compare the mean weight of a bag of chocolate chip cookies to the mean that the industry claims. Clearly outline your null and alternative hypothesis statements.
• Consider why your research question is important.
• Outline how you would use each of the steps of the four-step hypothesis test process to answer the research question.
• Think about how using a t test could help your analysis. How is the outcome from the t test used to support the claim made?
