a. Using the equation 1 + 3.322logN, classify the data in equal class intervals. b. What is the frequency of reserves in each interval? Generate the cumulative frequency distribution d. Generate the cumulative relative frequency and the decumula- tive relative frequency distribution. Plot the frequency distribution as a histogram and the cumula- tive relative frequency as an ogive. f. Using the information obtained above; what is the (a) proba- bility of reserves greater than 48,000 Stb, (b) probability of reserves less than 100,000 Stb, and (c) probability of reserves between 160,000 Stb and 43,000 Stb.
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.
