A certain estimate in normally distributed with mean 500 and standard deviation 10 the distribution of Estimates can be split into 4 groups lower tail, bottom half of the body, top half of the body, and upper tail Using the 3 numbers estimate= mean-1.1*stdev, Estimate=mean, Estimate=mean+1.1*stdev wok out the values A,B and C in the table below Region= Lower tail, Estimate<500 and |estimate-500|>A proportion B Bottom half of the body= Estimate<500 and |estimate-500|500 |estimate-500|>A Proportion B A. none of them correct B. A= 0.5 B= 0.0668, C=0.4332 C. A=0.1 B= 0.1587, C=0.3413 D A=11 B=0.3643, C= 0,1357
