A cholesterol drug company wants to market their drug to women if their cholesterol is in the top 13%. If you are to calculate the value of cholesterol serves as the cutoff, which of the following statements is correct? Assume cholesterol levels are distributed normally with a mean of 188 mg/dL and a standard deviation of 24. a) a. the correct area for the correct z value is .3500 b) b. the cutoff value is [188 + 24] c) c. the correct z value for the cut off value is 1.035 d) d. the cut off value is 215
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.
