Determine whether each of the following statements is true or false. This is a randomized, designed experiment. A) B) The data show no strong evidence of violating the assumption that the three populations have the same standard deviation. C) An ANOVA cannot be used on these data because the sample sizes are different. An ANOVA cannot be used on these data because the data show D) very strong evidence of non-Normal population distributions.

Question
(Ch12) At what age do babies learn to crawl? Does it take longer to learn in the
winter when babies are often bundled in clothes that restrict their movement? Data
were collected from parents who brought their babies into the University of Denver
Infant Study Center to participate in one of a number of experiments between 1988
and 1991. Parents reported the birth month and the age at which their child was first
able to creep or crawl a distance of 4 feet within 1 minute. The resulting data were
grouped by month of birth: January, May, and September:

Crawling age is given in weeks. Assume the data represent three independent simple
random samples, one from each of the three populations consisting of babies born in
that particular month, and that the populations of crawling ages have Normal
distributions.
