Sagot :
The critical value at the 0.010 significance level with 6 degrees of freedom are ±3.7074
How to determine the critical value?
The dataset is given as:
21.1, 25.1, 26.1, 27.1, 24.1, 31.1, and 31.1
The sample mean is:
[tex]\bar x = 22.1[/tex]
The significance level is
α = 0.010
Start by calculating the degrees of freedom using:
df = n - 1
Where n represents the sample size (n = 7)
So, we have:
df = 7 - 1
df = 6
Using the table for t critical values for a two-tailed test, we have:
Critical value = ±3.7074
Hence, the critical value at the 0.010 significance level with 6 degrees of freedom are ±3.7074
