sing the attached information, answer the following: 1. Fill in the blank: For these data, mileages that are greater than the mean of the mileages tend to be paired with used selling prices that are _____ the mean of the used selling prices. Choose one greater than less than 2. According to the regression equation, for an increase of one thousand miles in Cadet mileage, there is a corresponding decrease of how many thousand dollars in the used selling price? 3. What was the observed used selling price (in thousands of dollars) when the mileage was 37.7 thousand miles? 4. From the regression equation, what is the predicted used selling price (in thousands of dollars) when the mileage is 37.7 thousand miles? (Round your answer to at least one decimal place.)
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.
