The number of pounds of steam used per month by a chemical plant is thought to be related to the average ambient temperature (in °F) for that month. The past year's usage and temperature are shown in the following table. Month Temp(X) Usage(Y) Month Temp(X) Usage(Y) 21 185.21 July 68 621.55 Jan Feb 24 214.45 Aug 74 675.15 March 32 288.03 Sept 62 562.03 Apr 47 424.84 Oct 51 452.93 May 50 454.31 Nov 41 370.01 June 59 539.03 Dec 30 273.98 Estimate the intercept (beta0) and slope (beta1) regression coefficients. betao = beta1 =
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.
