A witness in a trial testified that he searched 21 cars, of which 12 were convertibles, 16 had out-of-state plates, and 4 were convertibles with out-of-state plates. Explain why the witness was not telling the truth. O The actual number of convertibles would have to be 8, which does not agree with the witness' testimony that 12 cars were convertibles. O The actual number of convertibles with out-of-state plates would have to be 12, which does not agree with the witness' testimony that 4 convertibles had out-of-state plates. O The actual number of cars he searched was 28, which does not agree with the witness' testimony that he searched 21 cars. O The actual number of cars he searched was 24, which does not agree with the witness' testimony that he searched 21 cars. Additional Materials M eBook
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.
