A weight-loss program wants to test how well their program is working. The company selects a simple random sample of 51 individual that have been using their program for 15 months. For each individual person, the company records the individual's weight when they started the program 15 months ago as an x-value. The subject's current weight is recorded as a y-value. Therefore, a data point such as (205, 190) would be for a specific person and it would indicate that the individual started the program weighing 205 pounds and currently weighs 190 pounds. In other words, they lost 15 pounds. When the company performed a regression analysis, they found a correlation coefficient of r = 0.707. This clearly shows there is strong correlation, which got the company excited. However, when they showed their data to a statistics professor, the professor pointed out that correlation was not the right tool to show that their program was effective. Correlation will NOT show whether or not there is…
Two types of plastic are suitable for an electronics component manufacturer to use. The breaking strength of this plastic is important. It is known that σ1 = σ2 = 1.0 psi. From a random sample of size n1 = 10 and n2 = 12, the values x̄1 = 162.5 and x̄2 = 155.0 are obtained. The company will not adopt Plastic 1 unless its mean breaking strength exceeds that of Plastic 2 by at least 10 psi. The P-value for the test H0: µ1 - µ2 = 10 versus H1: µ1 - µ2 > 10 is closest to:

A weight-loss program wants to test how well their program is working. The company selects a simple random sample of 72 individual that have been using their program for 18 months. For each individual person, the company records the individual's weight when they started the program 18 months ago as an x-value. The subject's current weight is recorded as a y-value. Therefore, a data point such as (183, 157) would be for a specific person and it would indicate that the individual started the program weighing 183 pounds and currently weighs 157 pounds. In other words, they lost 26 pounds. When the company performed a regression analysis, they found a correlation coefficient of r = 0.831. This clearly shows there is strong correlation, which got the company excited. However, when they showed their data to a statistics professor, the professor pointed out that correlation was not the right tool to show that their program was effective.

Assume that the population consists of only these eleven data points for y and z. Construct one sample for y and one another sample for z by using 5 data points which gives the maximum variance.If you still have some time, you can add your reviews about the contribution of Bessel’s Correction to the variance. Why do we use such correction and can the variance of any possible sample be larger than the variance of the population?
