Temperatures

[Maggiekidier]

Can someone please help me with this? A towns January high temperature average is 34°F with a standard deviation of 11°. Well in July the main high temperature is 77° and the standard deviation is 10. In which month is it more unusual to have a day with a high temperature of 56°? Round to three decimal places if needed

Have you considered finding the number of standard deviations from the mean?
