Answer 1

Ans : 10 ( - All satif assumption satisfied. and condition - because the data is randomly dists buted, & the data heat & time is independently distributed also data fosfors normally distributed roze . I @ Holla-lls-0 HA. lll-lls to The test statistics to t = 7 - 7 nz - Here X = {ai - 52042857 ni Y = Eyi 52.41286 s² (n-12s, ² + 112-12 52² - hitna-2 S2 - 6*1.1820 + 6x0.5332 7 + 7-2 32 - = 0.8576 2 = $0.8576 = 0.9261

t = 52.42857 - 52.41286 8.926153 0.03 t = P-value = p[t>0.03 ] = 0.975 Here p-value > 20.05 .: Еe gocepЕНо Accept the null hypothesis. There is no - sufficient enidence to support the claim that mean running time in heat 2 and heat s are different
