Games A 2019 Ipsos poll of 4,000 U.S. adults found that 65% play video games on their computer, gaming console, or smart phone. Using this sample result and a theory-based approach (and a Theory Based Inference applet), which of the following represents a three confidence intervals (90%, 95%, 99%) for the probability that a randomly selected American adult plays video games on their computer, gaming console, or smart phone? O 90%: (0.6376, 0.6624); 95%: (0.6352, 0.6648); 99%: (0.6306, 0.6694) 0 90%: (0.6306, 0.6694); 95%: (0.6352, 0.6648); 99%: (0.6376, 0.6624) 0 90%: (0.6376, 0.6624); 95%: (0.6306, 0.6694); 99%: (0.6352, 0.6648) O 90%: (0.6352, 0.6648); 95%: (0.6376, 0.6624); 99%: (0.6306, 0.6694) How do the midpoints of these three intervals compare? Midpoints are all the same. Midpoints are different. Midpoints get smaller as the confidence level increases Midpoints get larger as the confidence level increases Based on the confidence intervals, does the sample result provide strong evidence that more than 64% of all U.S. adults play video games on their computer, gaming console, or smart phone? Yes, because 64% is in the intervals. Yes, because 64% is not in the intervals. No, because 64% is in the intervals. No, because 64% is not in the intervals. Is it appropriate to use the theory-based approach to find the confidence intervals? Explain. O no, because the number of success and number of failures are both more than 10 O yes, because the sample size is more than 20 yes, because the number of success and number of failures are both more than 10 O no, because the sample size is more than 20
