1. The data from Technometrics described in exercise 8-51 considered the variability in repeated measurements of the weight of a sheet of paper.

The sample standard deviation from 15 measurements was 0.0083 grams. Does the standard deviation of weight measurements differ from 0.01 grams at = 0.05? Find the p-value for this test.

a.	No, standard deviationdoesn'tdiffer from 0.01 grams, and p-value = 0.0425.
b.	Yes, standard deviationdoesdiffer from 0.01 grams, and p-value = 0.425
c.	No, standard deviationdoesn'tdiffer from 0.01 grams, and p-value = 0.425
d.	Yes, standard deviationdoesdiffer from 0.01 grams, and p-value = 0.0425
