Chapter 14, Problem 7ICA

A technician tested a temperature probe by inserting it in boiling acetic acid (theoretical boiling points is 118 degrees Fahrenheit), recording the readings, removing and drying the probe, and repeating the process. The data are shown in the following table.

a. Determine the mean of probe 1.

b. Determine the median of probe 1.

c. A second probe was tested, yielding a mean of 97 degrees Fahrenheit and a median of 94.5 degrees Fahrenheit. If the data from probe 2 are as shown in the table, determine the missing data point.

d. If a probe has a standard deviation of 10 degrees Fahrenheit. What is the variance of the probe?
