Step-by-step explanation:

We know that , If p-value < \alpha , we reject the null hypothesis .

If p-value ≥ \alpha , we are fail to reject the null hypothesis .

As per given , we have

The p value for an independent samples t-test is 0.043.

The level of significance is \alpha=0.05

Since , 0.043 < 0.05.

i.e. p-value <  \alpha

It means  we reject the null hypothesis .

It means the null hypothesis is false.

Hence , the correct decision in this scenario is to favor the null hypothesis : False
