The Human Toxome Project (HTP) is working to understand the scope of industrial pollution in the human body. Industrial chemicals may enter the body through pollution or as ingredients in consumer. products. In October 2008, the scientists at HTP tested cord blood samples for 20 newborn infants in the United States. The cord blood of the "In utero/newborn" group was tested for 430 industrial compounds, pollutants, and other chemicals, including chemicals linked to brain and nervous system toxicity, immune system toxicity, and reproductive toxicity, and fertility problems. There are health concerns about the effects of some chemicals on the brain and nervous system. A table below shows how many of the targeted chemicals were found in each infant's cord blood. Based on the sample data, you have been asked to investigate if the mean number of targeted industrial chemicals to be found in an in infant's blood is more than 114. 79 137 145 83 147 156 160 94 116 121 100 144 159 151 156 123 114 139 126 99 1. Calculate the following summary information of the sample data correct to four decimal places as appropriate. Write your answers using appropriate statistical notations. a. The five-number summary b. the sample mean c. the sample standard deviation d. the standard error of the sample mean e. the percentile for 114 (see Example 2.18 of your textbook) 2. In the space below, draw a boxplot for this dataset.

The Human Toxome Project (HTP) is working to understand the scope of industrial pollution in the
human body. Industrial chemicals may enter the body through pollution or as ingredients in consumer
products. In October 2008, the scientists at HTP tested cord blood samples for 20 newborn infants in the
United States. The cord blood of the "In utero/newborn" group was tested for 430 industrial
compounds, pollutants, and other chemicals, including chemicals linked to brain and nervous system
toxicity, immune system toxicity, and reproductive toxicity, and fertility problems. There are health
concerns about the effects of some chemicals on the brain and nervous system. A table below shows
how many of the targeted chemicals were found in each infant's cord blood. Based on the sample data,
you have been asked to investigate if the mean number of targeted industrial chemicals to be found in
an in infant's blood is more than 114.
