Hello I have a problem that I can't seem to come to the proper conclusion with. It is as follows:
What is the probability that a randomly selected day in August will have a temperature greater than 85 but less than 100. Mean is 80 with a std dev of 8 assuming temperature is distributed normally.
I missed this on a test and I'd like to know where I went wrong so if someone could work it out step by step I would appreciate it very much. Thanks
