Use z scores to compare the given values.   Based on sample​ data, newborn males have weights with a mean of 3272.6g and a standard deviation of 660.7g. Newborn females have weights with a mean of 3039.4g and a standard deviation of 751.5g. Who has the weight that is more extreme relative to the group from which they​ came: a male who weighs 1500g or a female who weighs1500g?   Since the z score for the male is z=_________________ and the z score for the female is z=__________​, The ______________________ has the weight that is more extreme. ​(Round to two decimal​ places.)

Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.
