Nestling mass and nest humidity. Researchers investigated the relationship between nestling mass, measured in grams, and nest humidity index, measured as the ratio of total mass of water in the nest divided by nest dry mass, for two different groups of great titmice parents.2 One group was exposed to fleas during egg laying and the other was not. Exposed parents were coded as 1, and unexposed parents were coded as 0. Use the output above, obtained by fitting a multiple regression model with parallel lines for the two groups of parents, to answer the following questions.
(a) Identify the regression model for predicting nestling mass from nest humidity index for the two groups of great titmice parents.
(b) Based on your model, do you think that nestling mass was higher in nests of birds exposed to fleas during egg laying? Explain.
(c) What is the value of the regression standard error? Interpret this value.
(d) What is the value of the squared multiple correlation coefficient? Interpret this value.

Find the stationary distribution of the Markov chain.
A textile manufacturer estimates that it produces bolts of cloth with flaws following a Poisson distribution that has an average of one flaw per 200 feet of cloth.
Average rate of 65 per day with a standard deviation of 21. What is the productivity that during one week (5 working days) worker 1 will produce more than worker 2?
What are the estimated monthly sales for a particular region with a population of 796,000, per capita income of $6,940, and an unemployment rate of 6.0 percent?
Determine the margin of error in estimating the population mean. Sample of 68 college students yields a mean annual income of $3248. Assuming that the standard deviation = $885.
