1. Some phone apps measure the number of steps taken during a period of time. John downloaded an
app that reported data in a table like this:
Time
Steps
Steps taken
taken
(minutes)
600
4000
20
2400
25
3000
4200
3000
35
2000
1000
10
20
30
40
Minutes
(a) What are the variables of the problem? Identify independent and/or dependent variables of the
problem if any.
(b) Use the information from the table to graph the number of steps that John has taken over time.
Connect the points on your graph. Does this curve or is it a line?
(c) Explain why the graph tells you that John is walking at a constant pace.

- Helloarrow_forwardIn 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.

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. _______________________arrow_forwardUse 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.

Also name the best type oftransformation needed to "straighten" the plot.Note: Part of the transformation shouId involve subtracting 1900 from the year soyou're working with more manageable numbers.Now try some transformations to get the data as close to linear as possible.(Use your calculator to transform the data, and try scatterplots of the differenttransformations). Then find the regression line, r, and r2.Tell which transformation worked the best and back it up by showing:• A scatterplot of the transformed data with the least-squares regression equation andline, r, and r-squared.• A plot of the original data with the regression equation converted to a non-linearequationarrow_forward
