The correct option is A because

The statement makes sense. There is 95% probability that the confidence interval limits actually contain the true value of the population mean, so the probability it does not fall in this range is 100%−95% =5%.

From the question we are told that:

Confidence interval $CI=95\%$

Mean $\=x =1.9-3.5hours$

Level of significance (of the alternative hypothesis)

$\alpha=100-95$

$\alpha=5\%$

$\alpha=0.05$

Generally

There is 95% probability that the confidence interval limits actually contain the true value of the population mean.

In conclusion

The it does not fall in this range is Level of significance (of the alternative hypothesis)

100%−95% =5%.
