Part B: (41 points) Problem-Solving Suggestion: Report all final answers to 2 decimal points, carry 3 decimals for intermediate calculations. 1) The basal or resting heart rate typically has a mean of 70 standard deviation of 10 bpm. A sample of 25 students relaxing before the Bio-stat midterm measured a mea (Hint: first determine if this is a Z-test or t-test… Z-test if Population Std. Dev. Is k beats per minute (bpm) with a n = 75 nown) (6-pts) Construct a 95% confidence interval for μ . a. (2-pts) Z or t value associated with 95% CL = b. (2-pts) Standard Error (SE) A. C. (2pts) Margin of Error (M) = d. (2-pts) LCL= 01 B. (2-pts) Based on the Confidence Interval,is the basal heart rate for these 25 students significantly different from 70? Yes /No 2) Selif-competency test scores are taken before and after watching a YouTube video on how to measure blood pressure. The Paired data are BeforeAfter 75 61 67 75 Delta (After- Before) 76 72 78 73 21 (total) A. (6-pts) Given: Standard Deviation of the Delta column: 6.75, find i. (2-pts) Sample Size, na ii. (2-pts) Degrees of Freedom, df ii. (2-pts) Mean of the Deltas, , . B. (11-pts) Test the to see if the video had a significant impact in competency. I.
