Question

Given the linear correlation coefficient r and the sample size n, determine the critical values of r and use your finding to state whether or not the given r represents a significant linear correlation. Use a significance level of 0.05. r = 0.105, n = 15

Answer #1

Solution :

significance level of 0.05. r = 0.105, n = 15 , df = n -2 = 13

**Critical value of r = 0.514**

**The given r does not represents a significant
correlation.**

Given the linear correlation coefficient r and the sample size
n, determine the critical values of r and use your finding to
state whether or not the given r represents a significant linear
correlation. Use a significance level of 0.05. r=−0.816, n=5
A.Critical values: r=plus or minus±0.950, no significant
linear correlation
B.Critical values: r=plus or minus±0.878, significant linear
correlation
C.Critical values: r=0.950, significant linear correlation
D.Critical values: r=plus or minus±0.878, no significant
linear correlation

(a) Suppose n = 6 and the sample correlation coefficient is r =
0.908. Is r significant at the 1% level of significance (based on a
two-tailed test)? (Round your answers to three decimal places.) t =

Conclusion:
Yes, the correlation coefficient ρ is significantly
different from 0 at the 0.01 level of significance.
No, the correlation coefficient ρ is not significantly
different from 0 at the 0.01 level of
significance.
(b) Suppose n = 10 and...

Determine whether the given correlation coefficient is
statistically significant at the specified level of significance
and sample size.
