A new group of IQ tests are standardized to a Normal Model, N(110,14). Draw a model for these IQ scores in the show your work area. 1. use the textbox tool to insert the data values at the correct tic marks (std dev marks)
2. Clearly label the normal model with dashed horizontal lines and arrows to show the 68-95-99.7 Rule on the normal curve in the show your work area. (you can also use shading to show the different percentages) The first one has been done for you.
Also answer:
What percent of the data values fall between the IQ's of 96 and 124?
Note: 10 of the points for this problem come from the 'show your work' section, I will grade this portion.
Using the Normal Distribution in #1:
What % of the IQ scores are above 110?
Answer as a percent and include the correct symbol (%)
Then shade the correct area in the 'show your work' section.
Use your Normal Distribution half sheet:
What percent of the data is between one standard deviation below the mean and 2 standard deviations above the mean?
Check the shaded area in the show your work section. Enter your answer as a percent, use the symbol.
Shade part of the shaded region so your answer will be marked correct.
Use your Normal Distribution half sheet:
What percent of the data is between the two points at: two standard deviation below the mean and the mean?
Check the shaded area in the show your work section. Enter your answer as a percent, use the symbol.
Shade part of the shaded region so your answer will be marked correct.
Use your Normal Distribution half sheet:
What percent of the data is between the points: two standard deviation below the mean and one standard deviations above the mean?
Check the shaded area in the show your work section. No work needed by you. Enter your answer as a percent, use the symbol.
Shade part of the shaded region so your answer will be marked correct.
