Solution- Q=0:0) n= 802, X=518 5-6459 ß = 518 SO2 Null and Alternative hypothesis 220.5 # : ps. 0-5 test statistic is, P P PU-P 0.6459 -0.5 0-5 (1-0.5) 802 11459 0.0177 2=8.24 P-value = P(2> 2 -8.24) = 0 p-volue 2X=0.0) Rejeet the sull hypothesis because the p-value is less than or equal to the significance level 2 Conclusion: There is not sufficient evidence to support the claim that most medical malpoaetice lawsuits are dropper or dismissed Scanned with CamScanner
