T is the waiting time in seconds for a customer care representative of TechCo to respond to a customer's first question in an online chat session. You are given that T~ N( 19.1, 3^2). Find: P(T< 17)
Can anyone help. I put into my TI-84 calculator the normalCDF(0,16,19.1,3) but get nowhere near the answer which is 0.0620.
Where am I going wrong?
