A bank manager develops a new system to reduce the time customers spend waiting for teller service during peak hours. The manager hopes the new system will reduce waiting times from the current 9 to 10 minutes to less than 6 minutes.

Suppose the manager samples 100 customer waiting times. The manager thinks the new waiting time is shorter than six minutes.

What is an appropriate null and alternate hypothesis if we think the true population mean is less than 6 minutes?

Note: Remember that we always think the alternate hypothesis is correct. Also, the null hypothesis is always the opposite of the alternate hypothesis. The null hypothesis also always contains an = in the form of less-than-or-equal-to (written < = ), greater-than-or-equal-to (written > = ), or simply equal-to (written = ) Please explain your answer:
