We wish to see if the electronic control indicating the oven temperature for a certain model oven is properly calibrated. Four ovens of this model are selected at random. The electronic control on each is set to 300°F; after 1 hour, the actual temperature of each is measured. The temperatures measured are 305°F, 310°F, 300°F, and 305°F. Assume that the distribution of the actual temperatures for this model when the electronic control is set to 300°F is Normal. To test if the electronic control is properly calibrated, we will test the following hypotheses: H0: μ = 300 versus Ha: μ ≠300. Based on the data, what is the value of the one-sample t statistic?
