QuestionBig babies: The National Health Statistics Reports described a study in which a sample of 322 one-year-old baby boys were weighed. Their mean weight was 25.1 pounds with standard deviation 5.3 pounds. A pediatrician claims that the mean weight of one-year-old boys is greater than 25 pounds. Do the data provide convincing evidence that the pediatrician's claim is true? Use the α=0.05\alpha=0.05 level of significance and PP-value method with the (3) Critical Values for the Student's t Distribution Table.
Part: 0/50 / 5 \square
Part 1 of 5 (a) State the appropriate null and alternate hypotheses. H0:H1:\begin{array}{l} H_{0}: \square \\ H_{1}: \square \end{array}
This hypothesis test is a (Choose one) \nabla test. \square

Studdy Solution
Determine the type of test.
Since we are testing the mean with a known sample standard deviation and a relatively large sample size, we use a one-sample t-test.
This hypothesis test is a one-sample t-test.
The hypotheses are:
H0:μ=25H1:μ>25 \begin{array}{l} H_{0}: \mu = 25 \\ H_{1}: \mu > 25 \end{array}
This hypothesis test is a one-sample t-test.
