hello, would you please help me check my answers for question 2, 3 and 4? I really apreciate that! The table in attachment gives the data from historical election percent participation for the 18-24- year-old age group in US presidential elections from 1964 to 2012. For example the point (16, 40) represents the year 1980, x = 16 = 1980 – 1964, which had a participation rate of 40% for the 18-24-year-old age group in US presidential election. Type up your responses to the following 6 parts to this problem. There is no need to type the questions, just your responses, which can include screen shots. Create a scatter plot for the percent of participation of the 18-24-year-old group, y, as a function of years after 1964, x, using Desmos. See the video below for a review of how to create a scatter plot in Desmos. Create a linear model of the trend for the percent of participation of the 18-24-year-old group, y, as a function of years after 1964, x, using Desmos. Here is a video reviewing how to create a linear model in Desmos . . . Give your model in slope-intercept form, rounding to one decimal place. 3. Interpret the model describing what the slope and y-intercept mean in this situation, if anything. 4. Find the participation level for 2020, that is, what the model predicts for x = 56.
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.

Create a linear model of the trend for the percent of participation of the 18-24-year-old group, y, as a function of years after 1964, x, using Desmos. Here is a video reviewing how to create a linear model in Desmos . . .
Give your model in slope-intercept form, rounding to one decimal place.
3. Interpret the model describing what the slope and y-intercept mean in this situation, if
anything.
4. Find the participation level for 2020, that is, what the model predicts for x = 56.
my answers:
2. Y= -0.2x+47.5
3. Y intercept= (0, 47.5)
Slope= m= -0.2/1, if we increase one year the percentage will decrease 0.2%.
4. X=56 years after 1964.
Y= -0.2(56) + 47.5
Y= 36.3
I just want to make sure they are correct.
