Use the following information for questions:
How old are babies when they learn how to crawl? Does it take longer in the winter months because of all the bulky clothes? Data was collected at various pediatricians' offices. Parents indicated how old (in weeks) their baby was when they first started crawling (not scooting on the belly). Data for babies born in January, May and September is displayed below.
-The computer was used to analyze the data and the test statistic value was 3.82. At the 5% significance level, the critical value for this test is 5.99. What is the conclusion?
A) The results are significant and conclude that the median crawling ages appear to be equal for the three age group populations.
B) The results are not significant and conclude that the median crawling ages appear to be equal for the three age group populations.
C) The results are significant and conclude that the median crawling ages do not appear to be equal for the three age group populations.
D) The results are not significant and conclude that the median crawling ages do not appear to be equal for the three age group populations.

Since the test statistic value (3.82) is less than the critical value (5.99) at the 5% significance level, we fail to reject the null hypothesis. This indicates that the results are not significant, and we conclude that the median crawling ages appear to be equal for the three age group populations.
