Question

Heart failure is due to either natural occurrences (89%) or outside factors (11%). Outside factors are related to induced substances or foreign objects. Natural occurrences are caused by arterial blockage, disease, and infection. Suppose that 18 patients will visit an emergency room with heart failure. Assume that causes of heart failure between individuals are independent.

Round your answers to three decimal places (e.g. 98.765).

(a) What is the probability that 3 individuals have conditions caused by outside factors?

Probability = Enter your answer in accordance to the item a) of the question statement

(b) What is the probability that 3 or more individuals have conditions caused by outside factors?

Probability = Enter your answer in accordance to the item b) of the question statement

Mean = Enter your answer; Mean

Standard deviation = Enter your answer; Standard deviation

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
