answer part 2 frq styed please and show work 1. Because of the constantly evolving political climate around the United States, Gallup (who regularly conducts polls in the U.S.) conducted a poll just after the inauguration asking U.S. adults if they approve of the initiatives President Biden had implemented in his first few days in office. Another Gallup poll was conducted now that President Biden has been in office for a month asking U.S. adults if they approve of the initiatives President Biden had implemented after his first month in office. According to the first Gallup poll of 1500 randomly selected U.S. adults, 64% approved of the initiatives President Biden had implemented in his first few days in office. And according to the second Gallop poll of 1700 U.S. adults, 54% approved of the initiatives President Biden had implemented after his first month in office. Construct and interpret a 95% confidence interval for the change (difference) in the true proportion of U.S. adults…

4. Height is sometimes used to determine medicinal or nutritional needs. When a patient is bedridden, it can be difficult to determine height accurately. To deal with this issue, formulas have been developed that are based on a measurement that can be easily obtained on a prone patient Height in cm (females) 84.88 (0.24 x age) (1.83 x knee height) Height in cm (males) 64.19-(0.04 × age) + (2.02 × knee height) To find a patient's knee height, the knee and ankle of the patient are held at a 90° angle and the length from the heel to the knee is measured in centimeters. Age is in years. Based on: www.rxkinetics.com a. Find the height of an 80-year-old female patient whose knee height is 16 inches. Give the final result in inches. b. Test the formula on yourself to see how accurately your knee height and age predict your height.
