Statistics is used quite often in lawsuits. Maury Povich, a talk-show host, was recently sued for conducting improper paternity tests on his show. Yes, this was an article in the LA Times. An expert witness for a paternity lawsuit testifies that the length of a pregnancy is normally distributed with a mean of 280 days and a standard deviation of 13 days. An alleged father was out of the country from 240 to 306 days before the birth of the child, so the pregnancy would have been less than 240 days or more than 306 days long if he was the father. The birth was uncomplicated, and the child needed no medical intervention.What is the probability that he was NOT the father?What is the probability that he could be the father?HINT: Calculate the z-scores first, and then use those to calculate the probability.z score for 306 is 2z score for 240 is -3.07692 How do I calculate a and b in excel?

It is given that Mean, μ = 280 Standard deviation, σ = 13 We know that Z-Score, Z = ( X - μ )/σ…

Statistics is used quite often in lawsuits. Maury Povich, a talk-show host, was recently sued for conducting improper paternity tests on his show. Yes, this was an article in the LA Times. An expert witness for a paternity lawsuit testifies that the length of a pregnancy is normally distributed with a mean of 280 days and a standard deviation of 13 days. An alleged father was out of the country from 240 to 306 days before the birth of the child, so the pregnancy would have been less than 240 days or more than 306 days long if he was the father. The birth was uncomplicated, and the child needed no medical intervention.

What is the probability that he was NOT the father?
What is the probability that he could be the father?

HINT: Calculate the z-scores first, and then use those to calculate the probability.

z score for 306 is 2

z score for 240 is -3.07692

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 + ...
