Birth Weights For the sample data from Exercise 1, we get a P-value of 0.0291 when testing the claim that the sample is from a population with a standard deviation equal to 0.470 kg.

Assume that the test is conducted with a significance level given by a = 0.05.

a. What should we conclude about the null hypothesis?

b. What should we conclude about the original claim?

c. Does the vitamin supplement appear to affect the variation among birth weights?
