Suppose the tire brand (Brand 1 and Brand 2) was observed for each auto and the stopping distances for each brand are shown below: Tire Brand 1: 18, 18, 18, 20, 24 Tire Brand 2: 15, 22, 24, 24, 25, 26, 26 Suppose the researcher would like to see of the stopping distance of an automobile is different for the two tire brands. What is the response variable and what type of variable
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.
expect to see if you produced a histogram? Explain. c. Are there any outliers in the dataset? Justify with calculations you lean in the class. If there are outliers, identify them. d. Suppose the tire brand (Brand 1 and Brand 2) was observed for each auto and the stopping distances for each brand are shown below: Tire Brand 1: 18, 18, 18, 20, 24 Tire Brand 2: 15, 22, 24, 24, 25, 26, 26 Suppose the researcher would like to see of the stopping distance of an automobile is different for the two tire brands.
