When birth weights were recorded for a simple random sample of 12 male babies born to mothers in a region taking a special vitamin supplement, the sample had a mean of 3.658 kilograms and a standard deviation of 0.661 kilogram. Use a 0.05 significance level to test the claim that the mean birth weight for all male babies of mothers given vitamins is different from 3.38 kilograms, which is the mean for the population of all males in this particular region. Based on these results, does the vitamin supplement appear to have an effect on birth weight? P-value = 0.173 (Round to three decimal places as needed.) State the conclusion. A. Do not reject H0. There is sufficient evidence to support the claim that the mean birth weight for all male babies of mothers given vitamins is different from 3.38 kilograms. Vitamin supplements do appear to have an effect on birth weight. B. Reject H0. There is not sufficient evidence to support the claim that the mean birth weight for all male babies of mothers given vitamins is different from 3.38 kilograms. Vitamin supplements do not appear to have an effect on birth weight. C. Do not reject H0. There is not sufficient evidence to support the claim that the mean birth weight for all male babies of mothers given vitamins is different from 3.38 kilograms. Vitamin supplements do not appear to have an effect on birth weight. D. Reject H0.
