- Here are summary statistics for randomly selected weights of newborn girls: n=164, x=31.6 hg, s=7.2 hg. Construct a confidence interval estimate of the mean. Use a 98% confidence level. Are these results very different from the confidence interval 30.5 hg<μ<33.7 hg with only 18 sample values, x=32.1 hg, and s=2.7 hg? What is the confidence interval for the population mean μ? ______hg<μ<______ hg (Round to one decimal place as needed.) Are the results between the two confidence intervals very different? A. No, because each confidence interval contains the mean of the other confidence interval. B. Yes, because one confidence interval does not contain the mean of the other confidence interval. C. Yes, because the confidence interval limits are not similar. D. No, because the confidence interval limits are similar.Three products were used in a hot summer to keep the pool chlorine level high. Each product was used in 6 pools, and there was a total of 18 pools in the experiment. The same amount of chlorine was added to each pool (A, B, or C) and the conditions such as pool size, temperature, sun exposure etc. were similar. The chlorine levels (%) were measured and recorded after 24 hours of using the products. The percentages in the table below are the percentage of the chlorine added to the pool remaining after this 24 hours. The data is as follows: A 96 56 52 66 70 60 B 44 36 34 50 40 48 с 723227 34 40 20 24 a) Find the overall mean of the chlorine level across all the pools measured, and then find the mean of the chlorine level for each product.Here are summary statistics for randomly selected weights of newborn girls: n= 227, x= 32.7 hg. s=7.4 hg.
