Information about critical z value

Reference no: EM13113626

Use formula z=(mean of values in sample - mu subscript mean of values in sample) divided by (lower case sigma divided by sqrt number of values in sample)

The claim is mu = 73.4 and sample statistics include n=35, mean of values in sample = 69.5, and s=8.7
