A random sample of 100 two-month old babies is obtained, and the mean head circumference is found to be 40.6 cm. Assume that the population standard deviation is known to be 1.6 cm. Using a significance level of 0.05, test the claim that the mean head circumference of all two-month old babies is not equal to 40.0cm.d.) Determine the P-value. (Round to four decimal places.) e.) Determine the conclusion of the test. A) At the α=0.05α=0.05 level, we reject the null hypothesis and conclude the data are statistically significant. B) At the α=0.05α=0.05 level, we reject the null hypothesis and conclude the data are not statistically significant. C) At the α=0.05α=0.05 level, we fail to reject the null hypothesis and conclude the data are statistically significant. D)At the α=0.05α=0.05 level, we fail to reject the null hypothesis and conclude the data are not statistically significant.
