Below is a table from the General Social Survey. In 1986, respondents were asked how much they agreed or disagreed with the following statement. “Welfare helps prevent hunger and starvation”.   Male Female Row Total Strongly Agree 96 132 228 Agree 455 615 1070 Disagree 58 78 136 Strongly Disagree 9 17 26 Total 618 842 1460   What is the probability that a female says that she agreed?

Microsoft has a new online tool that tries to guess the age of the individual in the image. Students were to upload a photo of themselves and have the program determine their age (ToolAge) and then also enter their real age (True Age). A regression model was made to predict true age based on the tool age. This model uses information just from the men.  Predict the true age of a man if the age predicted by the Microsoft tool is 40.

In the Spring of 2017, a sample of 102 homes for sale in Gainesville was collected. The sale price and square footage of the homes were recorded.  The least squares regression equation was price = -58857+162.9*foot  For one house, the square footage was 1170 and the price was 137500 dollars. Find the residual. 

The below stem and leaf plot states the petal lengths (cm) of a sample of 150 irises.     What is the minimium petal length?

In the summer of 2011, the Chicago libraries recorded the number of participants per branch of the library versus the number of books read from that branch.  They wanted to predict the number of books read at each branch based on the number of participants in the summer program.  The least squares regression equation was  books read = -657.0 +24.74 participants For one branch of the library the number of participants was 184. The number of books read was 3513.  Find the residual.   

Look at the below scatterplot and determine what would be a reasonable value for the correlation coefficient. C1 and C3 represent someone’s rating of two different television programs on a scale from 0 to 1.0.  

In the summer of 2011, the Chicago libraries recorded the number of participants per branch of the library versus the number of books read from that branch.  They wanted to predict the number of books read at each branch based on the number of participants in the summer program.  The least squares regression equation was  books read = -657.0 +24.74 participants For one branch of the library the number of participants was 1142. The number of books read was 30310.  Find the residual. 

A group of individuals were asked to state their height and if they felt that their weight was about right, overweight or underweight. The below boxplot shows their height grouped by their weight status. What response had the highest third quartile height?  

A least squares regression equation was computed to predict the weight (lbs) of a 3 year old toddler based on the toddler’s height (in). The equation was yhat =  5.63 + 0.618x.  (The data set included toddlers between roughly 24 and 48 inches.)  Find the predicted weight of a toddler that was 35 inches tall.
