Explanation / Answer

1)

Whenever the test statistic value is greater than the critical value, we reject the null hypothesis H0.

Since in this case the test statistic value -1.978 is less than the critical value 1.786, so we do not have sufficient evidence to reject the null hypothesis H0. So, Henry would fail to reject the null hypothesis.

Hence 1st option is the correct option.
