True or False: The residual of a data point is the observed value minus the predicted value.

Forensic scientists can learn about events at a crime scene by collecting data. Ex: Properties of glass shards at a crime scene such as chemical composition can indicate what type of glass was broken at the scene. Possible types include building glass (building windows or doors), vehicle glass (car windows or doors), or household glass (lightbulbs, baking dishes). The fitted logistic regression model for predicting whether a glass shard is building glass based on sodium is: = 20.02+(-1.42) (sodium) 1+e20.02+(-1.42) (sodium) Calculate the log-odds that a glass shard with sodium = 13.08 is building glass. Ex: 1.23 C Calculate the probability that a glass shard with sodium = 13.08 is building glass.

How does linear regression differ from analysis of variance?

State whether the slope of a simple linear regression line is statistically significant, then the correlation will also always be significant?

A recent experiment included measuring the weight of a package of raw almonds.  This type of data would be considered a: Discrete variable or Continuous variable?

Is It Getting Harder to Win a Hot Dog Eating Contest?Every Fourth of July, Nathan’s Famous in New York City holds a hot dog eating contest. The table below shows the winning number of hot dogs and buns eaten every year from 2002 to 2015, and the data are also available in HotDogs. The figure below shows the scatterplot with the regression line.

The adjusted R-squared accounts for the amount of variance explained while also adjusting for the number of independent variables in the linear regression equation.   True or False

The data from the table below gives a regression that is a) reliable.   b) unreliable.   c) unable to determine the reliability.
