Determine whether the results appear to have statistical? significance, and also determine whether the results appear to have practical significance. in a study of a gender selection method used to increase the likelihood of a baby being born a? girl, 2048 users of the method gave birth to 1004 boys and 1044 girls. there is about aa 19% chance of getting that many girls if the method had no effect.
because there is a 19% chance of getting that many girls by chance, the method
(a) has statistical significance
(b) does not have statistical significance
(c) has practical significance
(d) does not have practical significance.

Mercury poisoning is dangerous overload of mercury within the body. a major source of mercury within the body, a major source of mercury poisoning is consuming fish that contain mercury. certain fish are more prone to having higher levels of mercury than others. the pie chart shows the distribution of four breeds of fish at a hatchery. the hatchery has approximately 6,000 fish. a biologist from the centers for disease control and prevention randomly test 5% of each breed of fish for mercury content. her findings are shown in the following table. based on the biologist's findings, if a single salmon is randomly selected from those that were tested, what is the probability that this particular fish would have a dangerous mercury level? a) 0.001 b) 0.004 c) 0.02 d) 0.08
