True or false

2: True or False 1) The correlation coefficient of -0.6 has a stronger association than a correlation coefficient of -0.8 2) The intercept is the y value when x equals slope. 3) The standard error is the standard deviation of the sampling distribution. 4) Keep other factor constant, the standard error with a sample size of 100 is larger than the standard error with a sample size of 50. 5) Keeping other factors constant, the 95% CI has a broader range with sample size 100 than with a sample size of 50. 6) Keeping other factors constant, the 95% CI has a broader range than the 99% CI. 7) One tailed test has a smaller significant level than two-tailed test. 8) Null hypothesis is the same as researcher's research hypothesis 9) A researcher is more likely to reject a null hypothesis at 0.05 level than 0.01 level 10) The t critical value is larger than the z critical value
