3. The data set lowbwt.csv contains information for a sample of 100 low birth weight infants born in two teaching hospitals in Boston, Massachusetts. Measurements of systolic blood pressure are saved under the variable name sbp and indicators of gender – with 1 representing a male and 0 a female – under the name sex. Answer the following questions using SAS. Please provide your SAS code and relevant SAS output. a. Construct a histogram of systolic blood pressure measurements for males and another histogram for females. Based on the graphs, do you believe that blood pressure is approximately normal for male and female infants? b. Test the hypothesis that among low birth weight infants, the mean systolic blood pressure for male infants is equal to the mean for female infants. Use a two-sided test at the 0.05 level of significance. What do you conclude?

Infants weighing less than 1,500 grams at birth are classed as "very low birth weight." Low birth weight carries many risks. IQ tests are designed to produce IQ scores varying Normally with standard deviation ?=15 . They are also scaled so that the mean score in a large population should be ?=100 . One study followed 113 male infants with very low birth weight to adulthood. At age 20 , the mean IQ score for these men was ?¯=87.6 ....
11. Birth Weights Data Set 4 "Births" in Appendix B lists birth weights from babies born at Albany Medical Center, Bellevue Hospital in New York City, Olean General Hospital, and Strong Memorial Hospital in Rochester, New York. Use a 0.05 significance level to test the claim that the four different hospitals have different birth weights with different medians. Data Set 4: Births TI-83/84 list names FLOS, MLOS, FBwT, MBWT. FCHRG, MCHRG [Separate lists provided for female (F) and male (M)...
Question 5 (Use Data Set 1) Before every flight, the pilot must verify that the total weight of the load is less than the maximum allowable load for the aircraft. The Bombardier Dash 8 aircraft can carry 37 passengers, and a flight has fuel and baggage that allows for a total passenger load of 6200 lb. The pilot sees that the plane is full and all passengers are men. The aircraft will be overloaded if the mean weight of the...
2. Using the data set of the Health Exam Results, conduct the following analysis between the variables of weight (WT) and Body Mass Index (BMI). Number the data set from 1 to 40, and select the following individuals: . Set 1 (Malo): 1, 5, 10, 13, 15, 18, 19, 24, 29, 31, 32, 33 .Set 2 (Fomalo): 4, 9, 15, 16, 17, 22, 23, 29, 33, 37, 38, 40 Draw a scatter diagram of the sample of 12 data set...
explaim the mechanisms amd toxological effects if type 1 diabetes in this article Exposure to arsenic in drinking water is associated with increased prevalence of diabetes. We previously reported an association of diabetes and urinary concentration of dimethylarsinite (DMAS"), a toxic product of arsenic methylation by arsenic (+ 3 oxidation state) methyltransferase (AS3MT). Here we examine associations between AS3MT polymorphism, arsenic metabolism and diabetes. Fasting blood glucose, oral glucose tolerance and self-reported diagnoses were used to identify diabetic individuals. Inorganic...
