You wish to determine whether eating carrots improves vision over time. You measure vision in 30 randomly chosen individuals who do not eat carrots regularly, and take the average of vision for each individual over one month. Then, those same individuals eat one carrot a day for the next three months, the final month of which vision is measured again.Your data pass all relevant normality testing. Please answer the following questions

1. What test do you use to determine whether carrots help vision?

2. What are your null and alternative hypotheses?

3. Given that mean vision before was 1.7, and after was 2.2, and that your test produces a p-value of 0.007, write a concluding statement

(Please answer ASAP)
