The weights of corn grew on a separate farm that was close to farm from question 2. The weights of these corn have a mean of 23 ounces, but have a standard deviation of only 2 ounces. A sample of the corn grown was selected, and the weights of the selected boxes are summarized in the histogram below 18 19 20 21 22 23 24 25 26 27 28 Weights of the corn ears Part A: If w is the weight of an ear of corn, which range of weights includes all of the weights of corn that are within 1.5 standard deviations of the mean?
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.
