Use the following information to answer questions 29 and 30. The focus to determine the number of injuries cases per day in your hospital. A study is conducted injuries cases recorded for 3 months. From this sample, the rate of injuries per day is 0.5.29. The distribution of the data is?................................................................... 30: Write down the value for the probability that 2 injuries cases are received per day...............................................
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.

Use this information to answer questions 1. The Centers for Disease Control (CDC) reported on trends in weight, height and body mass index from the 1960’s through 2002. The general trend was that people were much heavier and slightly taller in 2002 as compared to 1960. In 2002, the mean weight for men was reported at 191 pounds. Suppose that an investigator hypothesizes that weights are even higher in 2006 (i.e., that the trend continued over the subsequent 4 years). In order to test the hypotheses, we select a random sample of males in 2006 and measure their weights. Suppose we have resources available to recruit n = 100 men into our sample. We weigh each participant and compute summary statistics on the sample data. Suppose in the sample we determine the mean to be 197.1 and standard deviation to be 25.6.
