Question
Scenario: The health department has hired you to analyze 100 water samples taken near a beach on Lake Michigan. Your job is to analyze this data, reporting the numerical measures with a graphical representation of the data. You will also need to make a recommendation to close the beach or keep it open based on your data analysis. Below is a table containing the water samples from Lake Michigan near the beach suspected of having high levels of the coliform bacteria. You are to use this data to compute the statistics and construct the graphical representation.
Research Question is asking us to test and see if the population mean for the beach bacteria counts are lower than 200 fecal coliform counts.
