A fishing line manufacturer claims that the new X-25 series has a mean tensile strength ( ) of 25 psi and a standard deviation ( ) of 3 psi. To verify the claim, a ??sample of 25 specimens was tested and yielded the following results:
32 19 27 24 28 29 38 30 25 33 18 25 37 28 20 32 23 21 25 19 23 27 32 26 30
A. Compute the sample median, sample mode, sample mean, sample range, sample variance, average deviation and sample standard deviation. What do you think about the Manufacturer’s claim?
