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:$\mu$= 300 versus H_a: $\mu$ $\neq$ 300.Based on the data,what is the value of the one-sample t statistic? A)1.23 B)2.45 C)4.90 D)5.0

The one-sample t statistic is calculated using the formula: t = (x̄ - μ) / (s/√n), where x̄ is the sample mean, μ is the population mean, s is the sample standard deviation, and n is the sample size. Here, x̄ = 305, μ = 300, s = 4.08, and n = 4. Plugging these values into the formula gives t ≈ 2.45.
