Which of the following statistical methods should you use? two-sample t test ОООО М 0.0000 and X r W .... A A paired t test Linear regression An F test ص 3 × 45 We constructed a 95% confidence interval for a population mean. Which of the following would cause the confidence interval to become wider? Please select all that apply. Keep constant the sample mean, the sample standard deviation, and the sample size; increase the confidence level to 99%. Keep constant the sample mean, the sample standard deviation, and the sample size; decrease the confidence level to 90%. Keep constant the confidence level, the sample mean, and the sample standard deviation; increase the sample size.
