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, 1981 users of the method gave birth to 967 boys and 1014 girls. There is about a 15% chance of getting that many girls if the method had no effect. Because there is a 15% chance of getting that many girls by chance, the method couples would likely use a procedure that raises the likelihood of a girl from the approximately 50% rate expected by chance to the % produced by this method. (Round to the nearest integer as needed.) So this method does not have statistical significance. has statistical significance. does not have practical significance. has practical significance.Determine whether the sampling method described below appears to be sound or is flawed.

Foreign investment fell 350 percent during the 1990s." What is wrong with this statement? Choose the correct answer below. O A. The statement does not mention the initial amount of foreign investment. O B. If foreign investment fell by 100%, it would be cut in half. Thus, a decrease of 200% means that it would be totally eliminated, and a 200% is impossible. O C. The actual amount of the decrease in foreign investment is less than 100%. D. If foreign investment fell by 100%, it would be totally eliminated, so it is not possible for it to fall by more than 100%.A polling company reported that 27% of 2302 surveyed adults said that they play football.

Is there an incentive for car manufacturers to report values that are not accurate? Choose the correct answer below. O A. Yes, because consumers, in general, do not care about the weight of their car. In this case, the source of the data would be suspect with a potential for bias. O) B. No, because consumers, in general, would prefer to buy a car with a higher level of fuel efficiency. In this case, the source of the data would not be suspect and there would be no potential for bias. O C. Yes, because consumers, in general, would prefer to buy a car with a higher level of fuel efficiency. In this case, the source of the data would be suspect with a potential for bias. O D. No, because consumers, in general, do not care about the weight of their car.
