**8.1 Weight of Newborns**Below is the distribution of birth weights for all babies born in the United States in 2010:| Weight (grams) | Count ||---------------------|--------|| Less than 500 | 5,980 || 500 to 999 | 22,015 || 1,000 to 1,499 | 29,846 || 1,500 to 1,999 | 63,427 || 2,000 to 2,499 | 204,295|| 2,500 to 2,999 | 744,181|| Weight (grams) | Count ||---------------------|----------|| 3,000 to 3,499 | 1,566,755|| 3,500 to 3,999 | 1,055,004|| 4,000 to 4,499 | 262,997 || 4,500 to 4,999 | 36,706 || 5,000 to 5,499 | 4,216 |**Questions and Analysis:**a. **Histogram Representation:** - Construct a histogram displaying the birth weight data, using percentages instead of raw counts on the vertical scale. This will help in comparing data across different years or countries effectively. Discuss the trend of newborn weights.b. **Median Birth Weight:** - Determine which weight class contains the median birth weight.c. **Low-Birth-Weight Babies:** - Babies weighing between 1,500 grams (about 3 pounds 4 ounces) and 2,500 grams (about 5 pounds 8 ounces) are at higher risk of health issues, with those under 1,500 grams being at even greater risk. Calculate and display the proportions of newborns categorized as normal-weight, low-birth-weight, and very-low-birth-weight using a pie chart or bar graph.d. **Birth Weights Analysis:** - Formulate a few sentences summarizing the trends and findings regarding birth weights in the United States based on the data provided.

A researcher interested in determining if there is an association between head circumference and brain volume tested for linear correlation at the a= 0.05 significance level. She took a random sample of twenty adults and measured the head circumference and brain volume (using ultrasound) for each person in the sample. The table above gives the paired data for the twenty adults. The researcher determined there is positive linear correlation between head circumference and brain volume at the 0.05 level of significance. With that information answer the following questions. 1.) Since we've determined there is linear correlation between head circumference and brain volume from the output on the TI83/84 what is "a" the y-intercept of the regression line? A. a=.508 B. a=34.740 C. a=-110.572 D. a=-823.829 2. Since we've determined there is linear correlation between head circumference and brain volume from the output on the T183/84 what is "b" the slope of the regression? A. b=34.740 B. b=.508…
Blood pressure: A blood pressure measurement consists of two numbers: the systolic pressure, which is the maximum pressure taken when the heart is contracting, and the diastolic pressure, which is the minimum pressure taken at the beginning of the heartbeat. Blood pressures were measured, in millimeters of mercury, for a sample of 7 adults. The following table presents the results.
