Conduct a "quasi-experiment" by gathering the following data: age and height of 20 people. Then plot in a scatterplot (by hand or using a graphing software program such as Microsoft Excel). What does the data tell you?
Using the data you collected, calculate the mean, median, and mode, and then plot these on the same graph as the scatter diagram. What does the diagram tell you? Consider multiple contextual factors.

Develop a scatter plot with HRS1 (how many hours per week one works) as the dependent variable and age as the independent variable. Include the estimated regression equation and the coefficient of determination on your scatter plot. Does there appear to be a relationship between these variables (HRS1 and age)? Briefly explain and justify your answer. Calculate the slope (b1) and intercept (b0) coefficients and use them to develop an estimated regression equation that can be used to predict HRS1...

Data on the fuel consumption ?y of a car at various speeds ?x is given. Fuel consumption is measured in mpg, and speed is measured in miles per hour. Software tells us that the equation of the least‑squares regression line is ?̂ =55.3286−0.02286?y^=55.3286−0.02286x Using this equation, we can add the residuals to the original data.

Problem: You are interested in factors that predict the salaries
of catwalk models. You collected data from 231 models (attached
SPSS data file: supermodel_1.sav). For each model, you asked:
salary per day in dollars (on days when working (variable:
salary_2), age (variable: age), and how many years they have worked
as a model (variable: years). You also got a panel of experts from
various modeling agencies to rate the attractiveness of each model
as a percentage, with 100% being perfectly...

Questions 1) Plot the OD600 readings and cell concentration for each time point on a scatterplot with a line connecting the points. Have the measured data (OD600 and cell concentration) on the y-axis against the time on the x-axis using Excel (or other computer based data/graphing program). It is helpful to set the y-axis on a log scale for the cell concentration measurements. 2) Can you...
