I need help solving these problems. Please help me by answering and showing explanations.

Problem 1. The following data set represents a set of high temperatures in Austin over seven days, in degrees Fahrenheit. 61 60 75 78 58 72 75 (a What is the mean temperature? ) (b) What is the median? (C) What is the mode, using the data as given? (d) What is the mode, if we round each temperature to the nearest 5 degrees? (e) What is the sample variance? ) (f What is the sample standard deviation? Problem 2. Using the same data set as in Problem 1, imagine that the temperature on the rst day was something other than 61 degrees. The mean temperature would certainly be different; but how high could it have been before the median was different
