A package of shrimp is selected at random from those inventoried. What is the probability that a package of wild-caught shrimp came from Honduras? a. A package of shrimp is selected at random from those inventoried. Are the events ì"wild-caught" and "came from Honduras" independent? Explain your reasoning.
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.

Shrimp are often found in tropical climates and can be raised on farms or caught in the wild.
Elena was taking inventory of 1-pound shrimp packages at the end of the day at a seafood
market. She recorded the country of origin and whether the package contained shrimp that
were farm-raised or wild-caught.
27 packages of shrimp were farm-raised in Mexico.
40 packages of shrimp were farm-raised in Honduras.
52 packages of shrimp were farm-raised in Ecuador.
13 packages of shrimp were wild-caught in Mexico.
6 packages of shrimp were wild-caught in Honduras.
28 packages of shrimp were wild-caught in Ecuador.
