10. For a sample of 12 Tree, The volume of The lumber (y) (in cubic meTers) and The diameTer (x)(in cenTimeTers) aT The fixed heighT above ground level was measure. The following summary sTaTisTics were obTained: (7 poinTs) f = 36.1, sx = 4.2,? = 0.86, 53, = 0.98,?\" = 0.94- a. CompuTe The leasT-square regression line for predicTing volume from diameTer. b. The sTandard error of The slope of This leasT-squares regression line(sb) is approximaTely 0.08772. TesT for a significanT posiTive linear relaTionship beTween The Two variables The volume of The lumber (y) and The diameTer (x) by doing a hypoThesis TesT regarding The populaTion slope ,81. WriTe The null and AlTernaTe hypothesis and conclude The resulTs. (Assume ThaT The variable y follows a normal disTribuTion for each value of x.) Use P-value approach, by considering The 0.05 level of significance. JusT use Table. No crediT will consider for The quesTion which is solved by Technology
