Concept explainers

Inverse Normal Distribution

The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.

Mean, Median, Mode

It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.

Z-Scores

A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.

K Disk drives have been getting larger. Their capacity is now often given in terabytes (TB) where 1 TB = 1000 gigabytes, or about a trillion bytes. A survey of prices for external disk drives found the data shown to the right. For this data, we want to predict Price from Capacity. Complete parts a through i below. Click the icon to view the disk drive data and summary statistics. Disk Drive Data and Summary Statistics Capacity (in TB) 0.5 1.0 2.0 3.0 4.0 6.0 8.0 12.0 32.0 x = 7.611 SD(x) = 9.85 r = 0.987 --- Print Price (in $) 58.79 75.79 114.00 105.95 146.45 425.49 594.00 1074.00 4464.49 y = 784.329 SD(y) = 1420.27 Done X A. It indicates the price for a hard drive with no capacity. It is meaningless and should not be interpreted. B. It indicates the additional capacity in TB for each additional dollar of price.

People who live in Cape Carmel major reasons for their worry is that there are many homes built at, or nearly at, sea level along the coast of Cape Carmel. The total value of these homes is more than 100 million dollars. Ice melting increases the sea level. Global sea level is measured relative to the sea level in the year 1870. If the sea level in 1870 is represented by 0 inches, then Cape Carmel sea level has risen from 1 6.8 inches to 8.4 inches in the years from 1992 to 2012. If the sea level rises to 24 inches, it will have devastating effects on the homes along the coast of Cape Carmel. Many of the Cape Carmel residents want to know if, and when, they should sell their property before it is washed away into the sea. You must help residents understand more about the rising sea level in Cape Carmel to help them predict when they should sell their homes. 11.Create a graph (carefully scaled by hand, or on Excel) that shows BOTH the linear and the exponential model over ALL of the…
