Document Summary

Population proportion (p: p= proportion of peas that should be yellow, p= proportion of people with a certain disease. 0. 381- 0. 497 actually does contain the true value of the population proportion p. Confidence level: the probability 1- that the ci actually does contain the population parameter, assuming that the estimation process is repeated a large number of times. A 100(1- (cid:895)% ci for p is (cid:1868) (cid:1831) where (cid:1831)= (cid:3043) (cid:3044) (cid:3041) is (cid:272)alled the (cid:862)(cid:373)argi(cid:374) of error(cid:863) (cid:894)a(cid:374)d (cid:1869) = (cid:883) (cid:1868) ) (should only be used if n(cid:1868) (cid:1096) (cid:1009) a(cid:374)d (cid:374)(cid:1869) (cid:1096)(cid:1009)(cid:895) Margin of error (e): when data from a simple random sample are used to estimate a population proportion p, the difference between the sample proportion and the population proportion is an error. The maximum likely amount of that error is the margin of error. Example mendel bred green and yellow peas (picture) 428 were green and 152 blue.
