Find a 95% confidence interval for the difference in the corresponding values of . (Round your answers to three Assume X1 = 98, x2 = 123, SI-10, s2 = 12, decimal places.) Does this interval include more or fewer values than a 99% confidence interval? Explain your answer. O This interval includes fewer values because a smaller confidence level means that we need a smaller margin of error This interval includes fewer values because a smaller confidence level means that we need a larger margin of error. O This interval includes more values because a smaller confidence level means that we need a smaller margin of error. O This interval includes more values because a smaller confidence level means that we need a larger margin of error. 4. 16 points MintroStat6 7.E.076 My Notes Ask Your Teach Does bread lose its vitamins when stored?

Standard error, SE = sqrt [ s21 / n1 + s22 / n2 ] = 2.20907
degree of freedom, df = (s12/n1 + s22/n2)2 / { [ (s12 / n1)2 / (n1 - 1) ] + [ (s22 / n2)2 / (n2 - 1) ] } = 94.91 = 95
tcrit = +/- 1.9855
95% CI = (123-98) +/- 1.9855*2.20907 = (20.6139, 29.3861)
Answer : Option A.
This interval includes fewer values because a smaller confidence level means that we need a smaller margin of error
