Once the bank's home page has completely downloaded, the time an internet banking customer takes to click on the login button follows a normal distribution with a mean of 3 seconds and a standard deviation of 2 seconds. I.e. the login-click time has distribution N(3, 2²). The totaltime it takes for the home page to load and the user to click on the logn button will also follow a normal distribution. I.e. the download+login-click time has distribution N(, ²). State the parameters and below to 3 d.p.

• The mean of the download+login-click time is ______ seconds.
• Assuming that the covariance between the home page download time and the login-click time is zero, the standard deviation of the download+login-click time is ______ seconds.
• Assuming that the covariance between the home page download time and the login-click time is zero, the standard deviation of the download+login-click time is ______ seconds.
