A mаnufаcturer оf dish detergent believes the height оf sоаpsuds in the dishpan depends on the amount of detergent used. A study of the suds’ height for a new dish detergent was conducted. Seven pans of water were prepared. All pans were of the same size and type and contained the same amount of water. The temperature of the water was the same for each pan. An amount of dish detergent was assigned at random to each pan, and that amount of detergent was added to the pan. Then the water in the dishpan was agitated for a set amount of time, and the height of the resulting suds was measured. A plot of the data and the computer output from fitting a least squares regression line to the data are shown below. The horizontal axis is labeled “Amount of Detergent (in grams)” and ranges from 4.0 to 7.0. The vertical axis is labeled “Height (in millimeters)” and ranges from 30 to 65. The plotted points form an upward trend, showing that as the amount of detergent increases, the height of the foam also increases. A straight line of best fit runs through the points, illustrating a strong positive linear relationship between the two variables. The line begins near (4.0, 30) and extends upward to about (7.0, 65). Write the equation of the fitted regression line. Interpret the slope in context of the question. Interpret the correlation coefficient in the context of the question. Interpret the coefficient of determination in the context of the question. Interpret s = 2.0546 in the context of the question. Predict for 4 grams of detergent. Estimate the residual for 4 grams of detergent? Justify your answer. Please label each answer very clearly the space provided and show all work when necessary.

A mаrketing cоmpаny is interested in оbtаining a sample оf teenagers to view a trailer for a new movie to give their opinion on whether or not the trailer convinces them to see the full movie. They want to make sure that they get the opinions of both males and females. The company divides the population into two groups (males and females) and then takes a random sample of 60 teenagers from each group. This is an example of what type of sample?
