QUESTION 25 A sample of 35 families were asked how many pets they owned. Their responses are summarized in the following table. Number of Pets Number of Families 1 4 15 8. What is the median number of pets per family? O 2 pets. O 2.20 pets. O 15 pets. O 2 pets.
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.
![Box I contains 3 red and 2 blue marbles while Box II contains 2 red and 8 blue marbles. A fair coin is
tossed. If the coin turns up heads, a marble is chosen from Box I; if it turns up tails, a marble is chosen
from Box II. Find the probability that a red marble is chosen.
