... 5.22 The ideal number of children. "What do you think is the ideal number of children for a family to have?" A Gallup Poll asked this question of 1016 randomly chosen adults. Almost half (49%) thought two children was ideal.3 Suppose that p = 0.49 is exactly true for the population of all adults. G ...

... statistic comes from a random sample from a normal distribution. If the sample size is small (< 30), you should use a box-and-whisker plot or a normal probability plot to assess whether the assumption of normality is valid. If the sample size is large, the central limit theorem applies and the s ...

... To find the probability of an event: • We do not need to list all the elements in the sample space and the event. • What we do need is the number of elements in these sets. • The counting techniques that we learned in the preceding sections will be very useful ...

... A random variable is a variable that takes on values in its range with some associated probability. An example may be the number of heads in one flip of a fair coin which can take the value zero with probability ½ or the value one with probability ½. So a random variable is associated with a probabi ...
