Explanation / Answer

Here it is given that there are eight males. So n=8

Hence r critical value is 0.707 and given that r=0.995

Now as we know Reject your Null Hypothesis if your calculated value is greater than or equal to the Critical value; r rcritical (significant result). Accept your Null Hypothesis if your calculated value is less than the Critical value; r < rcritical (non-significant result)

As.here r is greater than critical value we reject the null hypothesis
