Question

Definition Definition Middle value of a data set. The median divides a data set into two halves, and it also called the 50th percentile. The median is much less affected by outliers and skewed data than the mean. If the number of elements in a dataset is odd, then the middlemost element of the data arranged in ascending or descending order is the median. If the number of elements in the dataset is even, the average of the two central elements of the arranged data is the median of the set. For example, if a dataset has five items—12, 13, 21, 27, 31—the median is the third item in ascending order, or 21. If a dataset has six items—12, 13, 21, 27, 31, 33—the median is the average of the third (21) and fourth (27) items. It is calculated as follows: (21 + 27) / 2 = 24.

Pineal Gland Study. Dr. Marquez hypothesized that fluoride had a deleterious effect on the pineal gland, which helps with sleeping. He measured the amount of fluoride in Americans and compared it to the fluoride level in Europeans, where its use in drinking water has been banned. He knew from reading the literature that the average fluoride level in Europeans was 40 parts per million (ppm). He collected a representative sample of 625 Americans and found that their fluoride level was 60 ppm with a standard deviation of 250 ppm. What is the value of the z-test statistic?

STAT 3128 Homeowrk Section Question 1. Let u denote the true average radioactivity level (picocuries per liter). The value 5 pci/L is considered the dividing line between safe and unsafe water. Would you recommend testing Ho: μ = 5 versus Ha: > 5 or Ho μ = 5 versus Ha: μ 5. A type II error in this case involves deciding the water is safe when it isn't. This is a very serious error, so a test which ensures that this error is highly unlikely is desirable. We prefer that the most serious error be a type II error because it can be explicitly controlled. One should test Ho: μ = 5 versus Ha> 5. A type I error in this case involves deciding the water is safe when it isn't. This is a very serious error, so a test which ensures that this error is highly unlikely is desirable. We prefer that the most serious error be a type I error because it can be explicitly controlled.
