Question

give a 90% confidence interval for the difference in mean weight gain after 21 days for chicks fed high-lysine corn or ordinary corn.

Is there good evidence that chicks fed high-lysine corn gain more weight? Let μ₁ and μ₂ be the mean weight gains of chicks fed high lysine corn and ordinary corn, respectively. State the hypotheses.

What is the test statistic? and P-value

18.24 (EX) More nutritious corn 1/6: Ordinary corn doesn't have as much of the
amino acid lysine as animals need in their feed. Plant scientists have developed
varieties of corn that have increased amounts of lysine. In a test of the quality of
high-lysine corn as animal feed, an experimental group of 20 one-day-old male
chicks ate a ration containing the new corn. A control group of another 20 chicks
received a ration that was identical except that it contained ordinary corn. Here
are the weight gains (in grams) after 21 days:

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 + ...
