**Question:** Would it be reasonable to use a normal model to describe the carbon monoxide concentration in a single measurement from this city?**Instruction:** Justify your decision.**Response Area:** [Blank text box for response] A research team is measuring the air quality of different parts of a city. The measurements show variations in carbon monoxide concentrations in parts per million (ppm) that average 16 ppm with a standard deviation of 12 ppm.

From the provided information, for the distribution of the carbon monoxide concentrations in parts…

In a certain population, triglyceride levels are approximately normally distributed with a mean of 150 mg/DL and a standard deviation of 42 mg/DL. Health experts define a level of 200 mg/DL or more as being high (and unhealthy, presumably). What percentage of this population would be considered to have an unhealthy triglyceride level? On your own piece of paper, draw a diagram, calculate a z-score, show your calculator commands and write your answer as a decimal to four place values. For example, probability = 0.0334 Take a picture of your work and upload where indicated.
Most water treatment facilities monitor the quality of their drinking water on an hourly basis. One variable measured is pH, which measures the degree of alkalinity or acidity in the water. A pH below 7.0 is acidic, one above 7.0 is alkaline, and a pH of 7.0 is neutral. One water-treatment plant has a target pH of 8.5. (Most try to maintain a slightly alkaline level) The mean and standard deviation of 1 hour’s test results based on 49 water samples at this plant are: = 8.42; s = 0.16 Does this sample provide sufficient evidence that the mean pH level in the water differs from 8.5? do in excel if needed
