You use this to calculate the test statistic, using μ = 74 (the supposed average temperature), σ = 1.00 (how much the temperature should vary), and n = 5 (how many data points you collected):

Now that you have the full data set, you are encouraged to calculate the mean, median, mode, and standard deviation yourself, and create your own graph as a refresher! (If you do, note that the data is in a frequency table, it is not a list of all of the scores individually...)

You use this to calculate the test statistic, using μ = 74 (the supposed average temperature), σ = 1.00 (how much the temperature should vary), and n = 5 (how many data points you collected): You compare your obtained z-statistic, z = 5.77, to the critical value, z* = 1.645, and find that z > z*.
