Weighted sample mean (x) _[(9.3/24.1)(53.00) +(6.3/24.1)(52.00) + <br />(8.5/24.1)(50.00)] = 51.68 <br />' (2.) Conclusion: Since the weighted sample mean for the reclaimed areas I, II, & III (51.68) <br />exceeds the value of the reference area (51.47), revegetation is deemed successful for the <br />sampling year and a t-test is not required for this parameter. <br />1 <br />1 <br />1 <br />' A-12 <br />
