Employees are observed working at a high-tech company for more than 1,000 hours. The employees spent just 11 minutes on average, on one project before being interrupted. Moreobver, after each interruption, they needed an average of 25 minutes to get back to the original project. As a manager, you implement a rule that you cannot interrupt one other between 1PM-3PM. And test how long they work on a project beofre being interrupted. Five employees reported the following times: 8, 12, 16, 12, 14 minutes What was the implementation of the rule effective at alpha=.01
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.
