Invoice errors in a billing system. In a study of invoice errors in a company’s new billing system, an auditor randomly sampled 90 invoices produced by the new system and recorded actual amount (A), invoice amount (I) and the difference (or “error”), x = (A – I). The results were a sample mean = $1 and standard deviation = $124 for the differences between the actual and invoice amounts. At the time that the sample was drawn, the new system had produced 1,500 invoices. Find an estimate for the true mean error per invoice of the new system. Interpret the results.
Determine whether the following graph can represent a variable with a normal distribution. Explain your reasoning. If the graph appears to represent a normal distribution, estimate the mean and standard deviation. Could the graph represent a variable with a normal distribution? Explain your reasoning. Select the correct choice below and, if necessary, fill in the answer boxes within your choice.A.No, because the graph is skewed right.B.No, because the graph is skewed left.C.No, because the graph crosses the x-axis.D.Yes, the graph fulfills the properties of the normal distribution. The mean is approximately enter your response here and the standard deviation is about enter your response here. (Type whole numbers.)

South Dakota prices vary $350,000: $400,000:$400,000:$425,000:$429,000: $440,000: $560,000: $585,000,: $585,000: $785,000 : $1,300,000. We found the following Mean = 569000 SD = 272703.1353 T score = .7113 P Value = .4932 We failed to reject the hypothesis. What is a 95% confidence interval and how would you create one for the population average price? What would it look like. How does this related to Central limit therorem? If you had a margin of error of $13,000 how large of sample would you need with a 90% confidence interval using the given tscore.
