Determine the mean annual amount spent on household consumption per family with a sample of 100 families, an average amount of $8,000 spent, and if the population standard deviation is $500,
For a 80% confidence level, z=1.282. The confidence interval estimate of the population mean annual amount spent is 7935.92 to 8064.08.
Show how Z=1.282 is calculated?
If the estimate is to be within 8 mpg of the true mean with 98% confidence and the estimated standard deviation is 22 mph, how large a sample size must be taken?

The mathematics SAT scores of the seven students in a mathematics seminar are 533, 553, 578, 586, 619, 626, and 633. Suppose that the student with the score of 533 drops the seminar and is replaced by a student with a score of 765.
What does confidence interval tell you? What does it mean? What 2 things can a researcher do to decrease width of a confidence interval? What are the effects?
This problem has to do with graphical plotting and computation for certain distribution. Please mention a detailed response to the questions listed with appropriate graphical and statistical data representation(s).
