A company manufactures snow shovels in batches of 62 and there is a 13% rate of defects. Round all answers to two decimal places. Find the mean: μμ = Find the standard deviation: σσ = Explain why this is a binomial experiment. Check all that apply. There are more than two outcomes for each beach volleyball Whether or not one randomly selected beach volleyball has a defect will not affect whether or not another randomly selected beach volleyball has a defect There is not a fixed number of beach volleyballs p = 13% remains constant from one randomly selected beach volleyball to another Whether or not one randomly selected beach volleyball has a defect will affect whether or not another randomly selected beach volleyball has a defect There are only two outcomes for each beach volleyball There are a fixed number of beach volleyballs, 62
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.
