The following table shows U.S. employment figures for 2014, broken down by educational attainment. All numbers are in millions, and represent civilians aged 25 years and over. Those classed as "not in labor force" were not employed nor actively seeking employment. Employed Unemployed Not in Labor Force Total Less Than High School Diploma 9.9 1.0 13.2 24.1 High School Diploma Only 33.9 2.2 25.9 62.0 Some College or Associate's Degree 35.3 2.0 18.4 55.7 Bachelor's Degree or Higher 48.8 1.6 16.9 67.3 Total 127.9 6.8 74.4 209.1 Find the probability that a person had attained a high school diploma only, given that the person was employed. Round your answer to two decimal places.
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.
