Identify the null and alternative hypothesislin symbolic and sentence form), test statistic, P-valuelor critical values), conclusion about the null hypothesis, and final condusion that addresses the original Don't just say Reject the null hypothesis or fail to reject the null hypothesis ). If you used the calculator, identify everything mentioned above in addition to which calculator functions and inputs for each field were used . A simple random sample of 15-year old boys from one city is obtained and their weights (in pounds) are listed below. What is the 0.01 significance level to test the claim that these sample weights come from a population with a mean equal to 147 lb. Assume that the standard deviation of the weights of all 15- year old boys in the city is known to be 16.7 146 140 160 151 134 189 157 144 175 127 164?

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 + ...
