Question

For each question

Identify the test statistic(round two decimal places)

Identify the P-value(round three decimal places)

Use the pulse rates in beats per minute (bpm) of a random sample of adult females listed in the data set available below to test the claim that the mean is less than 75 bpm. Use a 0.05 significance level. : Click the icon to view the pulse rate data Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses? O A. Ho = 75 bpm H: #75 bpm 0C. Ho: H> 75 bpm Hu<75 bpm B. Ho: u = 75 bpm HH <75 bpm OD. Ho u = 75 bpm H: >75 bpm

Answer 1

1. From n=50 the data, = 72.32, S221.366, Incã-po) Test statistic, t= √50 ( 72.32-75) - s 21.366 => t = -0.89 P-value = 0.18890742 ~ 0.189 2, from the data, x= 1.1844 , s=0.587 n 250 2 ſncx- Mo) √50 (1.1844-1) : Test statistic, to 8 0.587 => t= 2.22 P-value = 0.01553834 ~ 0.016

3. 6 - 29 0.58 na50 1 50 such p) √50 (0.5-0.5) Test statistic, Z= J6(1-P) 0.5 (1-0.5) => Z= 1.13 P-value = 0.129 2381 ~ 0.129 4. re = 0.812 n=165 J165 (0.812 - 0.8) Test statistic, Z = su Cô-p) JP(1-P) 0.8 (120.8) 27 z = 0.39 P-value = 0.6965365 21 0.697
