Find the mean temperature and standard deviation. Use the Statistical Table to establish the actual confidence level and confirm if the oven is fit for purpose? i) If the maximum permitted temperature is 95°C to prevent the food being overheated, use the Table again to confirm if this is likely to happen with 99 % confidence?
