two samples of n=5 subjects were analyzed with an independent -samples t-test, producing a t=2.295

does this indicate a significant difference in a two tailed test with alpha= .05?

Answer 1

Answer #1

We are given

Test is two tailed test.

n1 = 5

n2 = 5

df = n1 + n2 – 2 = 5 + 5 – 2 = 8

df = 8

α = 0.05

So, critical value by using t-table or excel is given as below:

tcritcial = ±2.3060

tobs= 2.295

tobs = 2.295 < tcritcial = 2.3060

So, we do not reject the null hypothesis

This does not indicate a significant difference in a two-tailed test with α = 0.05.

* For large samples one sample t-tests (n >120) use critical t scores of ±1.96 (for 95% confidence level two tailed test) or ±1.65 (for 95% confidence level one tailed test). * For small samples (n<120) use critical t score obtained from t-distribution table. You will need to calculate degrees of freedom, which is simply the sample size minus 1 (df = n-1) and use an alpha value of .05. * For comparing means between two samples (regardless of sample...
