HELP QUICK!!! A large bakery makes thousands of cupcakes daily in two shifts: shift A and shift B. Suppose that, on average, cupcakes from shift A weigh 130g with a standard deviation of 4 g. For shift B, the mean and standard deviation are 125g and 3g respectively. Assume independence between the shifts.

Every day the bakery takes a simple random sample of 40 cupcakes from each shift. They calculate the mean weight for each sample, then look at the difference between the sample mean (A – B).

Find the probability that the mean weigths from the samples are more than 6 grams apart from each other.

show all work by:

1. Defining the parameter(s)

2. Stating the assumptions

3. Stating the parameters

4. Finding a probability
