Use z scores to compare the given values. Based on sample data, newborn males have weights with a mean of 3204.8 g and a standard deviation of 770.8 g. Newborn females have weights with a mean of 3066.5 g and a standard deviation of 585.9 g. Who has the weight that is more extreme relative to the group from which they came: a male who weighs 1600 g or a female who weighs 1600 g? Since the z score for the male is z= and the z score for the female is z= (Round to two decimal places.) the V has the weight that is more extreme.

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.
