Question

The accompanying data represent the pulse rates (beats per minutes) of nine students. Treat the nine students as a population. Compute the z-s cores for all the students compute the mean and standard deviation of these 2-secores Click the icon to view the data table. (Round to Vie neatest hundredth as needed) Compute the mean of these z-second The mean of the z-second is ___ (Round to the nearest tenth as needed) Compute the stranded deviation of these z-second. The stranded deviation of these 2-seconds is __. (Round to the nearest tenth as needed)

Explanation / Answer

Population mean=U(let)=72.22

Population Standard deviation=7.82269

Now we calculate z score for individual student

Student 1 = 0.48321

Student 2 = -1.43429

Student 3 = -1.56212

Student 4 =0.99454

Student 5 =-0.02812

Student 6 =0.99454

Student 7 =0.99454

Student 8 =-0.53946

Student 9 = 0.09971

Mean of z scores = 0.00028

SD of z scores = 1
