Roman, a health data officer, was tasked to create a report describing the height of all the children ages 12-15 years in a small town in Rome. He measured the height of all the 37 children (ages 12-15 years) in that small town. Answer the table showing the number and percentage of children ages 12 to 15 years according to sex. Sex f Rel f Male <2 decimal places> Female <2 decimal places> Σf <2 decimal places>
According to the Center for Disease Control (CDC) during the 2018-2019 season the percent of Americans 18 and older who had a flu shot was 45.3%. We did a random sample of 500 Americans and found that 200 out of the 500 had a flu shot. Is there enough evidence at the 5% level that 45.3% or less of Americans 18 or older had a flu shot? Find the SE, z score, and p-value: a) SE = sqrt(0.40(1-.40)/500) = 0.0219, Z-score = (0.453 – 0.40)/0.0219 = 2.42, p-value = 0.87 b) SE = sqrt(0.453(1-.453)/500) = 0.223, Z-score = (0.40 – 0.453)/0.223 = -0.24, p-value = 0.4052 c) SE = sqrt(0.453(1-.453)/500) = 0.0223, Z-score = (0.453 – 0.40)/0.0223 = 2.38, p-value = 0.9913 d) SE = sqrt(0.453(1-.453)/500) = 0.0223, Z-score = (0.40 – 0.453)/0.0223 = -2.38, p-value = 0.0087
Look at the table that lists SAT scores before and after a sample of five students took a prep class and explain a Type I error and Type II error pertaining to the problem. Ho: u=0 Ha:u>0 Student 1 2 3 4 5 SAT score before class 700 840 830 860 600 SAT score after class 720 840 820 900 700
Naini, Cobourne, McDonald and Donaldson (2008) reported that a specific ratio of height to face length of 1 to 8.5 tended to be rated as most attractive—almost exactly what Da Vinci’s idealized Vitruvian Man, predicts as “perfection” in the human form. For this study, we want to see if there is a relationship between a person’s height and head circumference. We get a random sample of 40 people and measure both their height and their head size to the nearest centimeter. What test should you use and why?

Can you help with parts iv, v, and vi please? The size of the left upper chamber of the heart is one measure of cardiovascular health. When the upper left chamber is enlarged, the risk of heart problems is increased. The paper ("Left atrial size increases with body mass index in children")[https://www.ncbi.nlm.nih.gov/pubmed/19147240] (International Journal of Cardiology [2009]) described a study in which the left atrial size was measured for a large number of children age 5 to 15 years. Based on this data, the authors concluded that for healthy children, the left atrial diameter was approximately normally distributed with a mean of 26.4 mm and a standard deviation of 4.2 mm. i) Use `plotDist` to draw the probability density function of the left atrial diameter. ii) Generate 50 sample measurements of the left atrial diameters and plot the measurements using a histogram. iii) Approximately what proportion of healthy children have left atrial diameters less than…
