I am struggling to calculate the percentage using the standard normal curve and whilst applying z scores to it. This is the method that I have been taught but I do not understand it best. Please help me with this method if possible.
Variance = 17.84
Standard deviation = 4.22
Using the standard normal curve, and the data obtained from the histogram (Listed above), please help me answer the following questions:
Is a patient that stayed X = 10 days considered as being an extreme or typical length of stay? (show all your data analysis and justify your response in one sentence)
What percentage of the patients stayed longer than this? What percentage of the patients stayed less than this? Please show me how to calculate this properly.
b. Is a patient that stayed X = 17 days considered as being an extreme or typical length of stay? (Justify your response in one sentence) What percentage of the patients stayed longer than this? What percentage of the patients stayed less than this?

The cholesterol levels among females aged 50 and over are approximately normally distributed with a mean of 235 mg/dL and a standard deviation of 20mg/dL. What is Mrs. Brown's cholesterol level?

The least squares regression line for using X to predict Y was found to be y^=365+0.18xy^=365+0.18x. For trees in a given area, if the traffic flow is 14,000 cars per week, predict the lead content in their bark. Note: the traffic flow given in this question is NOT in the same units as the values used to calculate the line. Given value of x = 14,000 cars per week equals how many cars per day Predicted Value of y is how many micrograms per gram of dry weightarrow_forward
- When engaging in weight-control (fitness/fat burning) types of exercise, a person is expected to attain approximately 60% of his or her maximum heart rate. For 20-year-olds, this rate is approximately 120 bpm. A simple random sample of one hundred 20-year-olds was taken, and the sample mean was found to be 107 bpm, with a standard deviation of 45 bpm. Researchers wonder if this is evidence to conclude that the expected level is actually lower than 120 bpm. To determine this, we test the following hypotheses: Ho: H= 120 versus H₂ μ< 120 Suppose the mean and standard deviation obtained were based on a sample of size 25 rather than 100.arrow_forwardThe scores on a psychology test were normally distributed with a mean of 65 and a standard deviation of 4.
