Hello I need help answering these 2 questions for Sunday 9/30/18 please help!

1-Suppose we repeatedly took samples of size 25 households, averaged their incomes, and recorded

these means in a histogram. Sketch a reasonable distribution that would fit this histogram. Indicate

the mean and standard deviation on your sketch. Explicitly state the values of the mean and the

standard deviation of this sample-mean distribution.

2- Suppose I take a sample of Utica households and before I begin calculating the mean of their incomes

I tell you that there is a probability of 1.66% that the sample mean will be greater than $52,500.

Use this information to determine how many households are in my sample
