Given the rooa sarety guidelines and your confidence interval estimate from above, does it appear that the mercury in tuna sushi is too high for consumption? Explain for credit.
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.

A food safety guideline is that the mercury in fish should be below 1.0 part per million
(ppm) in order for fish to be safe for consumption. Listed below are the amounts of
mercury (ppm) found in tuna sushi sampled at different grocery stores in a major city.

Assuming that the population is normally distributed, construct a 99% confidence interval
estimate of the mean amount of mercury in the population. Round to the thousandths
