Given the df, confidence level, and t score, what is your decision about the null hypothesis? a) df = 21, 95% confidence level, 2-tailed test Critical t value: If t = 2.32, can you reject the null hypothesis (yes or no)? b) df = 18, 95% confidence level, 1-tailed test Critical t value: If t = 2.00, can you reject the null hypothesis (yes or no)? c) df = 24, 99% confidence level, 2-tailed test Critical t value: If t = 1.21, can you reject the null hypothesis (yes or no)?
Given the df, confidence level, and t score, what is your decision about the null hypothesis?
a) df = 21, 95% confidence level, 2-tailed test
Critical t value:
If t = 2.32, can you reject the null hypothesis (yes or no)?
b) df = 18, 95% confidence level, 1-tailed test
Critical t value:
If t = 2.00, can you reject the null hypothesis (yes or no)?
c) df = 24, 99% confidence level, 2-tailed test
Critical t value:
If t = 1.21, can you reject the null hypothesis (yes or no)?
d) df = 11, 99% confidence level, 1-tailed test
Critical t value:
If t = 3.15, can you reject the null hypothesis (yes or no)?
e) df = 23, 90% confidence level, 2-tailed test
Critical t value:
If t = 1.34, can you reject the null hypothesis (yes or no)?
