Explanation Given: In a 562 angioplasty procedures, the average hospital cost of an angioplasty/stint surgery for heart attack is $57,417 with a standard deviation of $3,584. Procedure used: To solve applied problems involving the mean, standard deviation, and a normal distribution of a population: 1. Locate the mean and the desired values on the normal curve. value − population mean population standard deviation = number of standard deviations from(above or below) the mean 2. Highlight the desired regions of the normal curve based on the conditions of the problem. 3. Add the percentages associated with the highlighted regions in Step 2. Calculation: The population mean is $57,417, the standard deviation is $3,584 and the value is between $57,417 and $61,001. Here, the cost $57,417 is nothing but the mean. It is enough to find the number of standard deviations from the mean for the cost $61,001. Substitute the given values in the formula value − population mean population standard deviation as follows. Number of standard deviations from the mean = value − population mean population standard deviation = 61 , 001

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 tw…

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 o…

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 compar…

Question

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
