Distribution of Data - Bell Curve
A test was given to 250 students. The mean was 80 and the standard
deviation was 7. The shape of the data distribution was a Bell Curve.
.See the graph below
Use your knowledge of Bell Curves to estimate what % of the students
scored:
1) between 2 standard deviations to the left of the mean, and 1
S.D. to the right of the mean
2) more than 2 standard deviations to the right of the mean
3) less than 66

All it takes isone friend sharing your photo or updates with the public to create a very public viral trend.For this project you will use what you have learned about exponential functions to study what happens if a social media post is shared publicly. 1. Write an exponential function to represent the spread of Ben's social media post.2. Write an exponential function to represent the spread of Carter's social media post.3. Graph each function using at least three points for each curve. All graphs should be placed together on the same coordinate…
