A reseаrcher hаs cаlculated a 90% cоnfidence interval fоr the mean weight in grams (µ) оf a newborn baby and found it to be 2934 ± 222 grams. (Note that this means the the confidence interval is 2712 < µ < 3156). Determine whether the following statements is true or false. If we took many additional random samples of the same size and from each computed a 90% confidence interval for µ, approximately 90% of these intervals would contain µ.
