1) A technician tested two temperature probes by inserting their probes in boiling water, recording the readings, removing and drying the probes, and repeating the process. The results are shown below, with temperature readings in degrees Celsius: Probe 1 Probe 2 88.5 95.5 85.5 102 87 102.5 87.5 99.5 86 90.5 89.5 91.5 91 104.5 By writing a formula in Excel for each question, find each of the following (a) What is the mean of each probe? (b) What is the median of each probe? (c) What is the variance of each probe? (d) What is the standard deviation of each probe
