(b) A department store has 7,000 charge accounts. The comptroller takes a random sample of 36 of
the account balances and calculates the standard deviation to be N42.00. If the actual mean (1)
of the account balances is N175.00, what is the probability that the sample mean would be
between N164.50 and N185.50?
b. greater than N180.00?
less than N168.00?

:i need some real : a store sells shirts to the public at one pricing scale and wholesale at another pricing scale. the tables below describe the cost, y, of x shirts. (after tables) how do the slopes of the lines created by each table compare? the slope of the public table is 3/4 of the slope of the wholesale table.the slope of the wholesale table is 3/4 of the slope of the public table.the slope of the public table is 12 times greater than the slope of the wholesale table.the slope of the wholesale table is 12 times greater than the slope of the public table.
