Calculate the following quantities using Lxcel. (U yeu have Excel 2010 or latet, we suggest using its new functions.) Round your answers to four decimal places, if necessary. a. P(−2.00≤40≤1.00), where tro has a t distrbution with 10 degrees of freedom. b. P(-2.00 ≤1 tso ≤1.00), where tsoo has a t distribution with 100 degrees of freedom. How do you explain the difference between this result and the one obtained in part al? The variance uf t with a large df is than a t aith a small di, C. P−2.00≤Z≤1.00), ​ where Z is a standard normal random vanable. Cempore this pesult to the results obenined in parts a and b. How do you explain the diterences in theae probubstues? The varanci of z is than the variance of t. (4) (3) The variance od 1 whth a smat ulf in than a 1 with a large du!
