Attached is the paper using ANOVA, now: Prepare a paper examining a regression analysis on the collected data. Begin by describing the research issue, problem, or opportunity and the accompanying data. It has to be about the candy study, any ideas?
Is there any way you can help me determine the regression equation on the following problem. I have done all of it but part 5 See attached file for full problem description.
I What do you know about regression analysis? What is regression analysis good for? II TRUE/FALSE Forecasting Components 1-A trend is a gradual, long-term, up or down movement of demand. 2-A cycle is an up-and-down repetitive movement in demand. 3-A seasonal pattern is an up-and-down repetitive movement within
Is there error inherent in using correlation & regression? Explain. Discuss the notion that correlation does NOT necessarily mean causation, but two variables that ARE known to be causally related will be correlated.
Why would someone go to the "trouble" of calculating a least squares regression line? Where in your experience have you seen regressions applied?

Use a polynomial model for the data to answer the following questions. Round all numerical answers to 3 decimal places, and years to the year. 1. Today, how many square kilometers of the earth's surface are there per person? If this were a square, what would be the length of one side? 2. If the population continues to grow
1. Under what conditions would you use correlation and/or regression analysis? Include comments on the type of data needed and a work-related suggestion for their use. 2. During the years 1790 to 1820, the correlation between the number of churches built in New England and the barrels of Rum imported into the region was a

I have been interested in the number of patients in some hospital per quarter. I have collected data for 15 quarters. My friend ran some quick calculations on the data and told me that 72% of the variation in patients can be explained, but the other 28% is still a mystery. I want to determine the regression equation, but first w
Refer to the data in the table that was provided by a geologist and the National Park Service obtained at Old Faithful geyser at Yellowstone National Park. The duration values are times (in seconds) of an eruption, the interval values are times (in minutes) to the next eruption, and the height values are heights (in feet) of the
