true or false H) If the sum of squared error terms is the same for two lines that are fit through the same scatter plot of data, then the two lines must be identical. I) If one data point from a population has a z-score of 2.7, then this data point must be larger than the population mean.
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.

scatter plot of data, then the two lines must be identical. -
I) If one data point from a population has a z-score of 2.7, then this data point must be larger than the population mean.

J) A population standard deviation cannot be negative.
(1). Check whether the given statement is true or false:
The given statement is: If the sum of squared error terms is the same for two lines that are fit through the same scatterplot of data, then the two lines must be identical.
The two lines are plotted on the same scatterplot and their sum of squared error terms are equal, that means both the lines must be identical, as the error term is the difference of actual value and the predicted value.
Therefore, the given statement is true.
