(d) What is your conclusion?
O Reject Ho. We can conclude that there is a significant difference in the proportion of E. coli in organic vs. conventional produce.
Reject Ho. We cannot conclude that there is a significant difference in the proportion of E. coli in organic vs. conventional produce.
Do not reject Ho. We can conclude that there is a significant difference in the proportion of E. coli in organic vs. conventional produce.
Do not reject Ho. We cannot conclude that there is a significant difference in the proportion of E. coli in organic vs. conventional produce.
