A particular fruit's weights are normally distributed, with a mean of 525 grams and a standard deviation of 29 grams. If you pick 7 fruits at random, then 20% of the time, their mean weight will be greater than how many grams? Give your answer to the nearest gram. A tutor work this problem out for me but i dont understand how the z score fo 0.20 is 0.84. I am seeing that 0.20 is = 0.5793 fomr the standard distribution table. Please cn you send a picture of the 0.84 showing on the z table. Thank you
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.
