Here are summary statistics for randomly selected weights of newborn girls: nequals199, x overbarequals27.9 hg, sequals7.6 hg. construct a confidence interval estimate of the mean. use a 99% confidence level. are these results very different from the confidence interval 26.3 hgless thanmuless than30.7 hg with only 20 sample values, x overbarequals28.5 hg, and sequals3.5 hg? what is the confidence interval for the population mean mu? 26.5 hgless thanmuless than 29.3 hg (round to one decimal place as needed.) are the results between the two confidence intervals very different? a. yes, because the confidence interval limits are not similar. b. yes, because one confidence interval does not contain the mean of the other confidence interval. c. no, because each confidence interval contains the mean of the other confidence interval. d. no, because the confidence interval limits are similar.

On the way home from visiting his family, vincent’s plane cruised at an altitude of 3.2 × 10^4 feet. he had heard that a man named felix baumgartner skydived from an altitude of 1.28 × 10^5 feet. vincent wants to know how much higher felix went on his skydiving trip. question 1 you have already seen how adding numbers works in either scientific notation or standard notation. but can you subtract numbers in scientific notation and get the same results as subtracting in standard notation? to find out, first solve vincent’s problem in standard notation. part a write the cruising altitude of vincent’s plane in standard notation.
