Answer #1

ANSWER:_

Probabilty of one chld boy =P(B1G2 +G1B2+B1B2) =0.512*0.488+0.488*0.512+0.512*0.512=0.761856

hence probabilty of other child boy given first one is boy =0.512*0.512/0.761856 =0.344086A

    Assume that 2000 births are randomly selected and exactly 1009of the births are girls. Use subjective judgment to determine whether the given outcome is​ unlikely, and also determine whether it is unusual in the sense that the result is far from what is typically expected. Determine whether exactly 1009 girls out of 2000 randomly selected births is unlikely. A. It is unlikely because the probability of this particular outcome is very​ small, considering all of the other possible outcomes. B.It...

    When two births are randomly selected, the sample space for genders is bb, bg, gb, and gg. Assume that those four outcomes are equally likely. Construct a table that describes the sampling distribution of the sample proportion of girls from two births. Does the mean of the sample proportions equal the proportion of girls in two births? Does the result suggest that a sample proportion is an unbiased estimator of a population proportion? For the entire population, 1 2' the...
