MORE BENEFITS OF EATING ORGANIC
Using specific data, we find a significant difference in the proportion of fruit flies surviving after 13 days between those eating organic
potatoes and those eating conventional (not organic) potatoes. This exercise asks you to conduct a hypothesis test using additional
data. In this case, we are testing
Họ : Po = Pc
Ha: Po > Pc
where p, and p. represent the proportion of fruit flies alive at the end of the given time frame of those eating organic food and those
eating conventional food, respectively. Use a 5 % significance level.
Effect of Organic Bananas After 25 Days
After 25 days, the proportion of fruit flies eating organic bananas still alive is 0.45 , while the proportion still alive eating conventional
bananas is 0.42. The standard error for the difference in proportions is 0.029.
