He following statement applies to unrestricted random sampling without replacement. indicate whether this statement is true or false. d. it is likely that five different random samples from the same population could produce five different estimates of the true population mean.

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
