r represents a significant linear correlation.
Step-by-step explanation:
GIven : Linear correlation coefficient: r = 0.543
Sample size: n= 25
Significance levle:
Degree of freedom : n-2 = 25-2=23
Now, we check r critical value table for value with df = 23 and .
Critical value = ±0.396 [From r critical value table]
Since r = 0.543 > 0.396, that means there is significant linear correlation.
Hence, r represents a significant linear correlation.
