In response to customer surveys a candy company has recently increased the size of the chopped nuts used in its caramel nut bar. The marketing manager is concerned that the change will affect the variability in the cooking temperature and compromise the taste and consistency of the candy. The head cook took a random sample of 27 bathes and found the standard deviation if the temperature 1.15 Degrees Fahrenheit. Realizing this is only a point estimate, the marketing manager has requested a 98% confidence interval estimate for the population variance in the cooking temperature.
