We wish to see if the dial indicating the oven temperature for a certain model oven is properly calibrated. four ovens of this model are selected at random. the dial on each is set to 300°f, and after one 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 dial is set to 300°f is normal. to test if the dial is properly calibrated, we will test the following hypotheses: h0: μ = 300 versus ha: μ ≠ 300. are the data statistically significant at the 5% significance level? yes, because the sample mean = 305°f, which is much higher than 300°fno, because the p-value is greater than 0.05no, because a difference of 5°f (between and μ) as compared to 300°f is very small (insignificant)
