A bakery is considering buying one of two gas ovens. The bakery requires that the temperature remain constant during a baking operation. A study was conducted to measure the variance in temperature of the ovens during the baking process. The variance in temperature before the thermostat restarted the flame for the Monarch oven was 2.4 for 15 measurements. The variance for the Kraft oven was 3.1 for 18 measurements. Does this information provide sufficient reason to conclude that there is a difference in the variances for the two ovens? Assume measurements are normally distributed and use a 0.02 level of significance. (a) Find F. (Give your answer correct to two decimal places.) (ii) Find the p-value. (Give your answer correct to four decimal places.) (b) State the appropriate conclusion

Question

18/1

A bakery is considering buying one of two gas ovens. The bakery requires that the
temperature remain constant during a baking operation. A study was conducted to measure
the variance in temperature of the ovens during the baking process. The variance in
temperature before the thermostat restarted the flame for the Monarch oven
was 2.4 for 15 measurements. The variance for the Kraft oven
was 3.1 for 18 measurements. Does this information provide sufficient reason to conclude
that there is a difference in the variances for the two ovens? Assume measurements are
normally distributed and use a 0.02 level of significance.
(a) Find F. (Give your answer correct to two decimal places.)
(ii) Find the p-value. (Give your answer correct to four decimal places.)
(b) State the appropriate conclusion.
Reject the null hypothesis, there is significant evidence to show a difference in variances.
Reject the null hypothesis, there is not significant evidence to show a difference in
Fail to reject the null hypothesis, there is not significant evidence to show a
variances.
Fail to reject the null hypothesis, there is significant evidence to
difference in variances.
