An experiment is done to determine whether eating sugary breakfast cereals has a negative effect on children's learning. One group of 6 children eats Cheerios every morning, whereas another group of 5 children eats Super-Chocolate- Frosted-Sugar-Bombs. Each afternoon the children are given basic skills tests to measure their learning for the day. The test scores for the Cheerios group has = 106 and standard deviation s% 5.2. The test scores for the Sugar-Bombs group has L = 96 and S1 = 5. Give a 98% confidence interval for the mean difference in test scores between the children who eat Cheerios versus Sugar Bombs. (a) The degrees of freedom using the conservative approach is: df = 95 (b) What is the value of for a 98% confidence interval? (give at least three digits after the decimal point). %3D (c) The confidence interval is from to

Question
An experiment is done to determine whether eating sugary breakfast cereals has a negative effect on children's learning. One group of 6 children eats Cheerios every morning, whereas another group of 5 children eats Super-Chocolate- Frosted-Sugar-Bombs. Each afternoon the children are given basic skills tests to measure their learning for the day. The test scores for the Cheerios group has I = 106 and standard deviation s1 = 5.2. The test scores for the Sugar-Bombs group has iz = 96 and S1 = 5. Give a 98% confidence interval for the mean difference in test scores between the children who eat Cheerios versus Sugar Bombs. (a) The degrees of freedom using the conservative approach is: df = 95 (b) What is the value of * for a 98% confidence interval? (give at least three digits after the decimal point).
