Answer to Question 1

A point estimate is an estimate of the population mean in the form of a single value, usually the sample mean. A confidence interval estimate is a specified range of numbers within which a population mean is expected to lie. It is an estimate of the population mean based on the knowledge that it will be equal to the sample mean plus or minus a small sampling error. The confidence level is a percentage or decimal value that tells how confident a researcher can be about being correct. It states the long-run percentage of confidence intervals that will include the true population mean.

Answer to Question 2

C
The three possible adjustments are to change the strategy and tactics, change the objective, and/or change the budget.

Hypertension is a silent killer because it is deadly and has no significant early symptoms. The danger from hypertension is the extra load on the heart, which can lead to hypertensive heart disease and kidney damage. This occurs without any major symptoms until the high blood pressure becomes extreme. Regular blood pressure checks are an important method of catching hypertension before it can kill you.

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.
