Statistics Bootstrap Distributions Assignment Create and analyze two bootstrap distributions using the data in the table below. A recent study examined the effect of diet cola consumption on calcium levels in women. A sample of 16 healthy women aged 18 - 40 were randomly assigned to drink 24 ounces of either diet cola or water. Their urine was collected for three hours after ingestion of the beverage and calcium excretion (in mg) was measured. The researchers were investigating whether diet cola leaches calcium out of the system, which would increase the amount of calcium in the urine for diet cola drinkers. The data are given below and are stored in the ColaCalcium data set. Diet Cola Water 1 50 1 48 2 62 2 46 3 48 3 54 4 55 4 45 5 58 5 53 6 61 6 46 7 58 7 53 8 56 8 48 Xw 1. By hand, find 10 bootstrap samples for diet cola and for water and sketch a dotplot showing the means of the samples. Also indicate the mean of the original data and the samples.

Does it appear that the mean calcium lost for women who drink diet cola is more than for women who drink water? Justify your answer. 4. Identify the Standard Error for each data set then construct a 95% confidence interval to estimate the size of the effect. 263 Data 1 Bootstrap Distributions Assignment Data 7 Data 8 Data 2
