Question

suppose that for a sexually active male drosophila fruit fly in a particular genetics lab the population mean lifespan is 38.9 days with a population standard deviation of 12.0 days when she experimentally removed all females from a simple random sample of 24 this drosophila flies in her lab a researcher in the slab found that 24 sexually inactive males had a mean lifespan of 62.5 days with a standard deviation of 14.1 days answer the questions below about the experiment and about testing weather sexual activity affects how long males Drosophila live. How do you find the Critical Value? How do you find theP-Value? reject or fail to reject the null hypothesis?

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 + ...
