Spontaneous dental hydroplosion is a disease that makes your teeth spontaneously turn into liquid. To investigate whether a new drug can prevent the onset of this disease, Jim Halpert decided to perform a study in which half of the fourteen employees at Dunder Mifflin Scranton received the drug and the other half received a placebo. Neither Jim nor the employees were told who received which treatment, and the number of times a subject #x27;s teeth turned into liquid was recorded. This is an example of (A) A double-blind experiment. (B) A matched-pair experiment. (C) An experiment, but neither double-blind nor matched-pair. (D) An observational study. In order to make thorough conclusions, the most important condition for statistical inference is usually that (A) the population distribution follows a Normal distribution exactly. (B) the data does not contain outliers. (C) the data follows an asymmetric, single-peaked distribution. (D) the data can be treated as a random sample from the population of interest. A study was taken at the large senior living retirement community, The Senior Living Community, and found that the average age of residents is 73 years with a standard deviation of 6.1 years. A simple random sample of 100 residents is selected and the sample mean age quot;x-bar quot; of these residents is calculated. You know that the random variable X has approximately a normal distribution because of (A) the central limit theorem. (B) the 68-95-99.7 rule. (C) the population that you #x27;ve sampled from does not have a Normal distribution. (D) the law of large numbers.
