Explanation / Answer

Hello,

Hope you are keeping well.

Now here, let us assume the Null Hypothesis(H0) to be such that X and Y have a statistically significant relationship,
while the Alternative Hypothesis(H1 ) is that X and Y do not have a statistically significant relationship.

We know that the p-value(probability value) of a test is the probability of seeing a result at least as extreme as the one that we actually see, assuming the null hypothesis is true. Here, we find after calculation that the P-value is 0.0588. If we take 5% confidence interval the p-value should be less than 0.05 to accept the null hypothesis. But as it stands we reject the Null Hypothesis because the p-value is 0.0588 > 0.05. Therefore we accept that H1 is true, i.e, X and Y do not have a statistically significant relationship.

So your option in the MCQ question is wrong as it will be the second option.
