Caffeine Taps: If instead of a 95% confidence interval, we calculated a 90% confidence interval for the mean of Taps, what would be different about this new confidence interval? The 90% CI would be narrower than the 95% CI The 90% CI would be centered at a higher number than the 95% CI The 90% CI would be wider than the 95% CI The 90% CI would be centered at a lower number than the 95% CI Caffeine Taps: If instead the study had used a larger sample size (e.g., N = 100), what would be different about the confidence interval (assuming the mean and standard deviation were the same)? The N=100 CI would be centered at a higher number than the N=20 CI The N=100 CI would be centered at a lower number than the N=20 CI The N=100 CI would be wider than the N=20 CI The N=100 CI would be narrower than the N=20 CI
