A study of compulsive buying behavior conducted a national telephone survey in 2004 of adults aged 18 and over. The total credit card balance had a mean of $3,399 and standard deviation of $5,595 for 100 compulsive buyers and a mean of $2,837 and standard deviation of $6,335 for 1,682 other respondents. Estimate the difference between the sample means for compulsive buyers and other respondents, and find the standard error of the difference. Let mu1 = the population mean total credit card balance for non-compulsive buyers Let mu2 = the population mean total credit card balance for compulsive buyers y(bar)2-y(bar)1= Standard error of the difference =

A study of compulsive buying behavior conducted a national telephone survey in 2004 of adults aged 18 and over. The total credit card balance had a mean of $3,399 and standard deviation of $5,595 for 100 compulsive buyers and a mean of $2,837 and standard deviation of $6,335 for 1,682 other respondents.
Estimate the difference between the sample means for compulsive buyers and other respondents, and find the standard error of the difference.
Let mu1 = the population mean total credit card balance for non-compulsive buyers
Let mu2 = the population mean total credit card balance for compulsive buyers
y(bar)2-y(bar)1=
Standard error of the difference =
