Explanation Given: The data of ‘‘U.S populations in five different age groups’ who use either a smartphone, a basic cell phone, or no cell phone at all’ is mentioned as, Age Group Smartphone Basic Cell phone No cell Phone 18–24 49% 46% 5% 25–34 58% 35% 7% 35–44 44% 45% 11% 45–54 28% 58% 14% 55–64 22% 59% 19% 65+ 11% 45% 44% Procedure used: “Step by step procedure to construct the sectioned bar graph: 1. The vertical line and horizontal lines called axes are drawn and labeled. 2. Different categories are placed along the horizontal axis. 3. An appropriate scale is placed along the vertical axis. 4. A vertical bar is drawn corresponding to each category based on the total frequency of all the groups. 5. Magnitude of each group in the vertical bar is colored differently.” Calculation: The total number of people is obtained by adding the users of smartphone, a basic cell phone, or no cell phone at all as, Age Group Smartphone Basic Cell phone No cell Phone Total Number

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 tw…

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 o…

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 compar…

What is the domain, range, increasing intervals (theres 3), decreasing intervals, roots, y-intercepts, end behavior (approaches four times), leading coffiencent status (is it negative, positivie?) the degress status (zero, undifined etc ), the absolute max, is there a absolute minimum, relative minimum, relative maximum, the root is that has a multiplicity of 2, the multiplicity of 3.

What is the vertex, axis of symmerty, all of the solutions, all of the end behaviors, the increasing interval, the decreasing interval, describe all of the transformations that have occurred EXAMPLE Vertical shrink/compression (wider). or Vertical translation down, the domain and range of this graph EXAMPLE Domain: x ≤ -1 Range: y ≥ -4.

use a graphing utility to sketch the graph of the function and then use the graph to help identify or approximate the domain and range of the function. f(x)= x*sqrt(9-(x^2))
