Hello, my name is Veronica Robles. I am in Math 1342 stastistics online at San Jacinto College. I am having trouble with this question. In a survey of a group of men, the heights in the 20-29 age group were normally distributed, with a mean of 68.3 inches and a standard deviation of 3.0 inches. A study participant is randomly selected. Complete parts b, and c. I am having trouble with part b and C in these questions. B.(b) Find the probability that a study participant has a height that is between 68 and 70 inches. The probability that the study participant selected at random is between 68 and 70 inches tall is ________ ( Round to four decimal places as needed.) c. Find the probability that a study participant has a height that is more than 70 inches. The probability that the study participant selected at random is more than 70 inches tall is ______ ( Round to four decimal places as needed) Can you please explain to me about this two problems that of the z score. I can have better understanding . Thank you.
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.
