A researcher is constructing a confidence interval which requires that the variance of temperatures in one sample be equal to the variance of temperatures in another sample. Sample 1 has an average temperature of 2.38 and standard deviation 1.43 degrees with n=6. Sample 2 has an average temperature of 4.075 and standard deviation 4.35 degrees with n=4. Test the null hypothesisof equal variancesagainst the alternative hypothesis of different variances at a significance level=.05.
