In comparing two regression models that were developed using the same data, we might say that the model with the higher R2 value will provide the most accurate predictions. Is this true? Why or why not? If not, what would be the better parameter to use to compare two regression models? Provide at least one example to illustrate your arguments.
A sample of n=16 observations is drawn from a normal population with µ=1000 andσ=200. Find the following.i) P(X >1050)
Assume that you have selected a random sample of 15 checks from a population of 800 checks. The checks you have selected are the following numbers: 664, 789, 650, 136, 365, 538, 800, 657, 110, 136, 398, 645, 214, 544, and 777. Based on this sample, evaluate the truth of the following statements regarding your findings. Describe why you feel each statement is true or false.
a. You have determined that Check No. 365 was not properly signed and was paid to a fictitious vendor. You conclude that fraud exists in the population.
b. You have determined that no fraud exists in the sample of 15 checks you evaluated. You conclude that no fraud exists in the population.
