A fish farm exercises quality control in its minnow production. At a certain age, minnows have an average (mean) weight of 12.7 g and must be between 12.3 g and 13.1 g or the fish farm is flagged for inspection. a) What is the confidence interval for these sizes?

b) What is the margin of error in this situation?

Let hh represent the number of hummingbirds and ss represent the number of sunbirds that must pollinate the colony so it can survive until next year. 6h+4s > 746h+4s> 74 this year, 88 hummingbirds pollinated the colony. what is the least number of sunbirds that must pollinate the colony to ensure that it will survive until next year?
