in a certain country, the probability that ababy that is born is a boy is 0.52 and the probably that a baby that is born isa girl is 0.48. a family has two children. if x is the number of girls born to a family, find the probability thatthe family has 0, 1, or 2 girls. (a) draw a treediagram showing the possibilities for each outcome.(b) create thebinomial distribution table for p(x) .

X-intercept=-5 y-intercept=2 the equation of the line is

A. find the power of the test, when the null hypothesis assumes a population mean of mu = 450, with a population standard deviation of 156, the sample size is 5 and the true mean is 638.47 with confidence intervals of 95 b. find the power of the test, when the null hypothesis assumes a population mean of mu = 644, with a population standard deviation of 174, the sample size is 3 and the true mean is 744.04 with confidence intervals of 95% c. find the power of the test, when the null hypothesis assumes a population mean of mu = 510, with a population standard deviation of 126, the sample size is 10 and the true mean is 529.44 with confidence intervals of 95
