\( =1=2 \) Use the 3 Cumulative Normal Distribution Table to find the \( z \)-score for which the area to its left is 0.09 . The \( z \)-score for the given area is \( \square \).

A population of 30 deer are introduced into a wildlife sanctuary. It is estimated that the sanctuary can sustain up to 500 deer. Absent constraints, the population would grow by \( 60 \% \) per year.

Select the correct answer. A local grocery store decides to offer a free piece of fresh fruit (banana or apple) to all shoppers in the produce department. The store is conducting an observational study to determine which type of fruit is selected more often. At the end of the first day, the store found that twice as many shoppers select an apple. The grocery store then repeats the observational study for 14 days. All studies yield similar results. What generalization can be made from the results of this study? A. Given the choice of any type of fruit, twice as many shoppers will select an apple. C. Given the choice of a banana or an apple, twice as many shoppers will select an apple. D. The results are inconclusive; therefore, a generalization cannot be made regarding which type of fruit is preferred by most shoppers.
