Faraway planet is populated by creatures called jolos. all jolos are either green or purple and either one - headed or two - headed. ballon, who lives on this planet, does a survey and finds that her colony of 852 contains 170 green, one-headed jolos; 248 purple, two - headed Jolos; and 430 one - headed Jolos. How many green Jolos are there in Balan's Colony? A. 138 B. 308 C. 422 D. 260
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.
(USE COLUMN 1)
Total number of one headed = 430 (given)
Green Jollos = 170 (given)
Given: For one headed Jollos
Total jollos = Green Jollos + Purple Jollos
430 = 170 + Purple Jollos
Purple Jollos = 430 - 170
Purple Jollos = 260 (One headed)
