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
H0??:?po?=?pcHa?:?po??>?pc
where po and pc 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 Potatoes After 11 Days
After 11 days, the proportion of fruit flies eating organic potatoes still alive is 0.67, while the proportion still alive eating conventional potatoes is 0.63. The standard error for the difference in proportions is 0.033.
