Use the Atmospheric Carbon Dioxide Concentration scatterplot below to answer the questions. Atmospheric Carbon Dioxide Concentration 1970-2012 400.00 380.00 2011, 391.63 360.00 340.00 y = 1.6178x - 2864.6 R = 0.994 320.00 300.00 1970 1975 1980 1985 1990 1995 2000 2005 2010 2015 Year Write a sentence explaining the value of the slope for this regression line. For every increase in year, the CO2 increases by 1.6178 ppm. For every increase in the CO2, the year increases by 1.6178 ppm. For every increase in year, the CO2 decreases by 2864.6. For every increase in the CO2, the year increases by 2864.6. not able to determine CO2 in ppm
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.
