Hello
In recent decades, the percentage of Americans who always wear their seatbelt has been on the rise. The following table contains data[1] between the years 1992 and 2011 (n, number of years after 1992) representing the percentage (P) of Americans who always wear seatbelts. The graph contains a plot of these points along with a “fitted” line, which models (or approximates) the data points. The equation for this line appears below the graph. n 0 4 8 12 16 19 P 70 75 79 83 87 91 P=1.07n+70.28 Estimate the percentage of Americans who always wear their seatbelt for 2002.

What type of graph is this, and is it displaying Ordinal, Interval, Nominal, or Ratio Data?
Can someone please answer this and tell me how to create a scatter plot in MS excel
We'll look at the Galton data frame from the mosaicData package: data(Galton)View(Galton)help(Galton) Here's a scatterplot of the heights of the mothers and the heights of their children: ***(YOU MUST CREATE THE SCATTERPLOT FROM INFO GIVEN) We would like to use the data to predict the height of a child from the height of her mother. As described in class and in the Course Notes, use the predict() function to predict the height of a child (the time of Galtons' study) if the child's mother was known to be 64 inches tall. Record your answer (without units) as a decimal number, correct to at least two decimal places. _______________________

Use the data given in the three scenarios below to produce scatter plots, determine the type of model demonstrated in each example and then answer the questions based on the graph you created. Scenario 1 Rescue 911 In a rural community, fire and paramedic crews must service a large region. They often cover 2 or 3 towns several kilometres apart. These crews travel, on average, 70 km/h to their destination. The Chief of Station 42 wants to determine the time required to reach the patient's home (response time) for his region. The station is located next to the local hospital. The Chief knows the distances to each community that he services, including Deerborn, the furthest community, at 55 km away. Using the data below, create a scatter plot showing the relationship between distance to patient and response time. Distance to Patient (km) Response Time (minutes) 10 8.6 15 12.9 40 34.3 50 42.9 55 47.1

Create a graph chart using in this situation: According to literacy in the country of OZ, youth literacy went up 7% since 2000. Here is the data: In 2000, only 43% of the youth population was literate. In the next census at 2005 it went up by 2%. After five years, the literacy rate was at 47%. During the most recent survey in 2015, the rate is already 50%
