r represents a significant linear correlation.

Step-by-step explanation:

GIven : Linear correlation coefficient: r = 0.543

Sample size: n= 25

Significance levle: $\alpha=0.05$

Degree of freedom : n-2 = 25-2=23

Now, we check r critical value table for value with df = 23 and $\alpha=0.05$ .

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.
