A research program used a representative random sample of men and women to gauge the size of the personal network of older adults. Each adult in the sample was asked to "please name the people you have frequent contact with and who are also important to you." The responses of 2824 adults in this sample yielded statistics on network size, that is, the mean number of people named per person was x=14.6, with a standard deviation of s=10.3 It is unlikely that the personal network sizes of adults are normally distributed. In fact, it is likely that the distribution is highly skewed. If so, what impact, if any, does this have on the validity of inferences derived from the confidence interval?A. It does impact the validity of the interpretation because the interpretation is based on highly skewed resultsB. It does impact the validity of the interpretation because the interpretation was based upon a sample instead of the entire population. C. It does not impact the validity of the interpretation because the interpretation is based on highly skewed results. D. It does not impact the validity of the interpretation because the sampling space of the sample mean is approximately normal according to the Central Limit Theorem.
