Suppose population 1 is alt blue cars sold at used car auctions, and the mean sate price of all such blue cars is $2,4S79 with a standard deviation of S3.691. Additionally suppose population 2 is ail rod cars sold at used car auctions. and the mean sale of all such red cars is $21,948 with a standard deviation of $4,028 If a random sample of 47 blue cars sold at used car auctions is selected and Xi= the mean sale price of the 47 blue cars in the sample is determined, and an independent random sample of 59 cars sold at used car auctions selected and x2= the mean sale price of the 59 red cars the sample determined. if appropriate describe completely the sampling distribution of x1- x2. Required:
What is the mean of the Sampling Distribution?
