Answer 1

Anso As by the given dates on internet users and scientific aw and winners, the Coppeet Scatten Hotels @ C * By the By the given data. if Bodennet usens =X and tward winnenst. then we have by Calculating x= 1747.31LY 257.7, ZXY=22128.03, IX'=138632.05 I72 5191.51 23X 22/28.03 - 1747.3x257.7 n expo - 2x271 1297138632,05 -1747.3%)(234 v En 2 X2-(2002[*: Iy9+ (28)3] 5190.51 - 257.73) n. 692 The Tinear Correlation coefficient in is 0.692 Null hypothesis and Alten refine, byopohesis ape a Ho pa 4 1770 Test statistic tan fon2 01692 14:39 3-2 23-2 10.6922 0.00026 P value = Conclusion: As Prolve 1820.05. there is sufficient evidence to support the claim that there is a linear Correlations between internet users and scientific award winners.
