CHAPTER TESTSolve the following problems completely.An article in the Journal of Environmental Engineering (1989, Vol. 115(3), reported theresults of a study on the occurrence of sodium and chloride in surface streams in centralRhode Island. The following data are chloride concentration y (in milligrams per liter) androadway area in the watershed x (in percentage).yyyX0.194.40.156.60.579.70.7010.60.6710.80.6310.90.4711.80.7012.10.6014.30.7814.70.8115.00.7817.30.6919.21.3023.11.0527.41.0627.71.7431.81.6239.5 MATH 403- ENGINEERING DATA ANALYSIS6.

The heights of people in a certain population are normally distributed with a mean of 63 inches and a standard deviation of 4.3 inches. Suppose that a normal model applies.The model that correctly shows the 68-95-99.7 rule (empirical rule) for tree diameter is model: C A B About 68% of heights fall in the range described by option between 54.4 and 71.6. above 67.3. between 50.1 and 75.9. between 58.7 and 67.3. below 58.7. What percent of people in this population have heights below 54.4?

The standard deviation of pulse rates of adult males is more than 11 beats per minute. This is a claim about a population proportion so a normal distribution is assumed. The claim undergoes a hypothesis test using a significance level of α = 0.05. The P-value based on sample data is calculated to be 0.345.4. Sketch a normal distribution curve and highlight the region of significance (also called critical region or rejection region).5. On your graph, next highlight the P-value. (The P-value means that there is a 34.5% chance that your results could be random or happen by chance).6. State a conclusion about the null hypothesis. (Reject H0 or fail to reject H0.)7. Without using technical terms or symbols, state a final conclusion that addresses the original claim.
