Question
Pls answer both parts for Upvote
a) Using the following g table, comment whether there is an association between hair lead content and blood hemoglobin
b. Below are Boxplots ordering the job-specific BPb levels for male and female workers in lead factories. Summarize the results presented by the graph. * means there is a significant exposure to lead.
Table 1. De of blood and hair ters Kyrgyzstan n-20 n-20 na20 Blood haemoglobin (g/L) 107 +7 95+3 95 90-99 98+8 mean + SD Median 90-115 76-115 Hair lead (ug'g) Median 5.04 0.02-36.00 8.86 4.89 1.13-27.40 2.71-50.10 Hair cadmium (ugig) Median 0.09 0.01-0.31 0.11 0.01-1.41 Range 0.06-0.50 Hair mercury (g'g) 0.07Explanation / Answer
a. Since there is no mean available for the hair lead content, the blood lead content and the hair lead content are compared on the basis of their median and range values. There seems to be no correlation between the two parameters since the values do not follow a consistent trend.
Further analysis can be prepared using the Kruskal-Wallis Test or the Mann-Whitney U test to see high resolution trendline, however still no relation woud be found.
b. Ony four sectors show women with high blood lead levels. Assembling, Packaging, Charging and Others.
The highest range of blood lead are seen in the Stearate sector where the lowest value is 5 and the highest value is 80.
The lowest range is seen in the charging section in women between 7-12.
Analysis -
Grinding: The mean lead content falls around 34 with a majority of the males in the 2nd quartile between 22-33. The group shows mean with variable levels of lead content as given by the graph whiskers, The overall range varies from 20-50.
Cutting: Overall Range:14-40 , Majority lies in first Quartile between 14-25.
Filling: Overall Range: 16-54 , Majority lies in fourth Quartile between 35-59.
Stearate: Overall Range: 5-80, Majority lies in fourth Quartile between 40-80.
Bullion: Overall Range: 10-50 , Majority lies in fourth Quartile between 31-50.
Powder: Overall Range: 7-28 , Majority lies in second Quartile between 15-20.
Casting: Overall Range: 5-35 , Majority lies in fourth Quartile between 24-35.
Formatting: Overall Range: 7-35, Majority lies in first Quartile between 7-18.
Assembling: Here both the men and the women suffer from lead exposure. In men the overall range is 7-26. With a majority lying in the first quartile between 7-15. In women, The ranges are 4 - 26. With a majority in the fourth quartile between 17-26.
Packaging: Here both the men and the women suffer from lead exposure. In men the overall range is 8-30. The majority lies in the third quartile between 15-20. In women, the range is 6-21 and majority lies in the scond quartile between 7-11.
Charging: Here both the men and the women suffer from lead exposure.. In men, the overall range is 4-24. Majority lies in the 3rd quartile between 10-15 with a mena of 10. In women, the overall range is 5-8. With a majority lying in the second quartile between 8-10.
Others: Here both the men and the women suffer from lead exposure. In men, the overall range is 5-34. While the third quartile predominates the majority of individuals with high lead exposure. It ranges from 10-18.
In case of females, The full range of exposure values is 5-21. Majority lies in the 3rd quartile between 7.5-10/
