Here are summary statistics for randomly selected weights of newborn girls: n=239, x=27.5 hg, s=7.7 hg. Construct a confidence interval estimate of the mean. Use a 95% confidence level. Are these results very different from the confidence interval 25.6 hg<μ<30.0 hg with only 12 sample values, x=27.8 hg, and s=3.5 hg? What is the confidence interval for the population mean μ? 26.726.7 hg<μ<28.928.9 hg (Round to one decimal place as needed.) Are the results between the two confidence intervals very different? A. Yes, because one confidence interval does not contain the mean of the other confidence interval. B. No, because each confidence interval contains the mean of the other confidence interval. C. Yes, because the confidence interval limits are not similar. D.

Need now max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
