Answer:“

No” would be the appropriate response. A further explanation is provided below.Step-by-step explanation:According to the question,

Number of observations,n = 20

Significance level,d = 5%

i.e.,

= 0.05

Calculated correlation,= 0.40

Critical correlation value will be:= 0.444

0.40” is far less than the critical correlation value i.e., “0.444“.So the above it the right response.
