- Here are summary statistics for randomly selected weights of newborn girls: n=243, x=27.2 hg, s=6.1 hg. Construct a confidence interval estimate of the mean. Use a 99% confidence level. Are these results very different from the confidence interval 25.9 hg<μ<28.7 hg with only 14 sample values, x=27.3 hg, and s=1.8 hg? What is the confidence interval for the population mean μ?Here are the summary statistics for randomly selected weights of newborn girls: n =247, x= 32.2 hg, s= 6.8hg . Construct a confidence interval estimate of the mean. Use 90% confidence level. Are these results very different from the confidence interval 31.0 hg < u < 33.2 hg with only 18 sample values, x= 32.1 hg and s=. 2.7 hg ? What is the confidence interval for the population mean u ? _ hg < u< hg _ (round to one decimal places as needed ? Are the results between the two confidence intervals very different ? a. Yes, because the confidence interval limits are not similar. b. No. because the confidence interval limits are similarc. Yes, because one confidence interval does not contain the mean of the other confidence intervald.A sample of freshman takes a reading comprehension test and their scores are summarized below. Sample scores: 16, 8, 8, 6, 9, 11, 13, 9, 10 a. if the mean for the general population on this test is m=12, can you conclude that this sample is significantly different from the population. Test with a=.05 b. Calculate a 90% confidence interval around your mean.
