The probability that the sample proportion surviving for at least 3 years will be less than71 % is?(Round to four decimal places as needed.)
About % of all female heart transplant patients will survive for at least 3 years.
female heart transplant patients are randomly selected. What is the probability that the sample proportion surviving for at least 3 years will be less than %?
Assume the sampling distribution of sample proportions is a normal distribution. The mean of the sample proportion is equal to the population proportion and the standard deviation is equal to

9. 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, assume the...
