7.2.9-T Question Help Here are summary statistics for randomly selected weights of newborn girls: n = 237, X = 27.5 hg, s= 72 hg. Construct a confidence interval estimate of the mean. Use a 99% confidence level. Are these results very different from the confidence interval 25.3 hg <<29.3 hg with only 18 sample values, x 273 hg, and s-2.9 hg? What is the confidence interval for the population mean u? ng<<ng (Round to one decimal place as needed)
Here are summary statistics or randomly selected weights of newborn girls: n-186, x-265 hg.-68g Construct a confidence interval estimate of the mean, Use a 99% confidence level Are these results very different from the confidence interval 24.6 hg < μ 27.6 hg with only 19 sample values x = 26.1 hg and s=2.3 hg? What is the confidence interval for the population mean μ? (Round to one decimal place as needed)
Here are summary statistics for randomly selected weights of newborn girls: n=150, x=27.5 hg, s=6.8 hg. Construct a confidence interval estimate of the mean. Use a 95% confidence level. Are these results very different from the confidence interval 26.8 hg
