Answer 1

Problem 3 Given mean u =330 and standard deviationo =50 Using empirical rule 3sigma limits are 68% of the data fall between 1sigma limits and they are ( H (280, 380) 95% of the data fall between 2sigma limits and they are 2 2) (230, 430) 99.7% of the data fall between 3sigma limits and they are o) (180,430)

Empirical distribution table is below 34% 34% 2.35% 13.5% 230 13.5% 2.35% 480 180 280 330 380 430

Using the above table a) About 68% of the data fall between 1 sigma limits and they are 280 and 380 grams b) of weight between 230 and 430 is =(13.5+34+34+13.5)%=95% c) of weight outside between 230 and 430 is =(100-95)%=5% d) of weight between 180 and 380 grams is =(2.35+13.5+34+34)%=83.85%
