Concept explainers

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.

Question

In the past, trout in Clearwater Creek were 14.5 inches long on average. A recent sample of 36 trout from
the creek found = 14.2, s 3.
a. Build a 99% CI for the current mean length of trout in Clearwater Creek.
Round all intermediate calculations to two decimals, then construct the Cl and enter like this: (min,max).
Note: if you use a built-in Cl command on a calculator/computer, you might get marked wrong due to
rounding. Use the formulas given in the text/notes.
b. Use your Cl to decide whether the mean length of trout in Clearwater Creek has changed from 14.5
inches.
No, the mean has not changed since the old value of u is right in the middle of the new Cl
O No, the mean has probably not changed since the new Cl contains the old value of u
O Yes, the mean has probably changed since the new CI does not contain the old value of u
O Yes, the mean has probably changed since the old value of u is not right in the middle of the new CI

A doctor works at a hospital estimate when to leave for work from his apartment; he decided to measure how long it takes him to go to the hospital every day. For one week, he records the time it gets him to drive from his apartment to the hospital, including searching for parking and reaching to his office. The data are as follows: M Eighty-one Min T Fifty-four Min W Seventy Min R Fifty-two Min F Forty-three Min 1- Will you recognize these times as a sample or a population? and way 2- Obtain the mean and the standard deviation for the time it requires him to go to his office at the hospital. 3- Lets say his roommate, who is working with him at the same hospital and same office, takes the train to the hospital.
