Question 10

The data set below contains total Medicare enrollment data for the state of California for the years 2013 - 2017. Estimate a linear trend regression model and forecast Medicare enrollment in California for the year 2020.

Year Enrollment
2013 5,300,177
2014 5,481,592
2015 5,653,896
2016 5,814,275
2017 5,965,489

Please round intermediate results to one decimal and your final answer to the closest integer.

(To facilitate grading, please enter only the number without commas separating thousands and millions. For example, if your final answer is 1 million, enter 1000000.)

The StatCrunch data set for this question contains the data measurements described in Question 11. (H0 : µ1 - µ2 ≤ 0 HA : µ1 - µ2 > 0) Assume that the two samples are dawn from independent, normally distributed populations that have different standard deviations. Use this data set and the results from Question 11 to calculate the p-value for the hypothesis test. Round your answer to three decimal places; add trailing zeros as needed. The p-value = [S90PValue]....

In 2004, the University of California education system drastically cut enrollment due to significant state budget cuts and asked 7,600 applicants to defer enrollment for two years after completing two years at a community college. Tuition costs remained fixed by the state. Demonstrate the situation described with supply and demand curves, carefully labeling any excess supply or demand for college admission. What is the market solution to the excess demand for college? What is a possible reason the market solution...

The data below contains the total costs and depths of 16 offshore oil wells. It is expected that cost is a linear function of the depth. (a) Write out the equation of the regression line. Interpret the slope and intercept in the context of this problem. Do they make sense? b) Test the hypothesis that the slope parameter is zero 4 different ways (ANOVA, t-test for β1, t-test for ρ, and a confidence interval for β1). (c) What is the...

The data set contains the weight (grams) of 10 mice before and after the treatment. Weight of the mice before treatment before: (200.1, 190.9, 192.7, 213, 241.4, 196.9, 172.2, 185.5, 205.2, 193.7) Weight of the mice after treatment after: (392.9, 393.2, 345.1, 393, 434, 427.9, 422, 383.9, 392.3, 352.2) Is there enough evidence in the data that the treatment increases the weight population average weight by at least 150 grams? Please answer with R programming code. Thanks!
