Question

Here is a sample data set that appears to be nearly normal (as suggested by the histogram).

What is the mean of this data set? (Report answer using the rules suggested in class: 1 more d.p. than the data.)
M=M=

What is the standard deviation of this data set? (Report answer using the rules suggested in class: 2 more d.p. than the data.)
SD=SD=

What is the z-score of the value 53.5 in this data set? (Report answer accurate to 3 decimal places with appropriate rounding. ALSO REMEMBER that it is best to use the unrounded MMand SDSD for this calculation, not the values reported above.)
z-score =

36.8	60.7	50.6	37.6	46.5	38.2	61.2
54.4	61.2	53.3	40.6	50.5	46.3	60.7
