As a part of your job you need to wait infants that are brought in for doctor appointments. A. List at least two examples of random errors that may occur in your measurement. B. What could be done to minimize the random errors? C. What procedures could be implemented to ensure the measurements are as accurate as possible?

Please answer a and b

The blood pressure in millimeters was measured for a large sample of people. The average pressure is 140 mm, and the SD of the measurements is 20 mm. The histogram looks reasonably like a normal curv Use the normal curve to estimate the following percentages. Choose the answer that is closest to being correct. A 19.1% B 30.9% C 38.2% D 69.1% E 68.27% A The percentage of people with blood pressure between 130 and 150 mm. B The percentage of people with blood pressure between 140 and 150 mm. D The percentage of people with blood pressure over 150 mm.

When should I use the One-sample t-test? Remember that some tests, such as chi squared, can be used under various circumstances. The goal of the test changes based on the situation. Pay attention to the specific conditions noted in parenthesis to ensure you are picking the correct goal. A. Test to compare frequency data to a specific population model B. Compares numerical data to a known mean. The null hypothesis is that the mean of the data equals the known mean. C. Test to see if the frequency data from a population fit a discrete probability distribution. D. Compare two treatment groups when a normal distribution cannot be assumed. E. Compare two treatment groups consisting of paired data when the data do not fit the normal distribution. F. Compare two treatments consisting of paired data where a normal distribution can be assumed. G. Compare two treatment groups of independent samples where the data meet the assumption that the data fit the normal distribution. H. Test the fit of…
