chicken. The correlation coefficient =.794‚ which means this does have a positive linear correlation. (1.2) Run a linear regression: Chicken price vs. consumption Chicken w/beef+pork+ beef Chicken consumption over time increases Chicken consumption=b0+b1*Income+b2*chicken price+b3*pork price+b4*beef price What’s the estimated regression equation? (5pts.) (1.3) Identify significant and insignificant variables. Does the chicken consumption statistically

Generate a scatterplot for income ($1‚000) versus credit balance ($)‚ including the graph of the best fit line. Interpret. This scatter plot graph is a representation of combining income and credit balance. It shows the income increasing as the credit balance increases. As a result of this data it can be inferred that there is

recent years however‚ students seem to be taking more care and responsibility during schoolies week‚ and their behaviour has generally improved. In the opinion piece “Parents who just won’t say ‘no’ to blame for schoolies scourge”‚ published in the Herald Sun on the 25th of September 2010‚ Rebecca Wilson contends in an alarming and critical tone‚ that parents must accept responsibility for the growing schoolies epidemic‚ and must learn to stand up to their kids if we are to purge this harmful event

zero. Why? This just means that there is no linear correlation between all three variables advertising/location/price. 4) Run regressions for each sales variable (s1‚ s2‚ s3) using P‚ A‚ L and independent variables. What do the regressions imply about the effect on price? Of advertising? Of location? In sales period one the coefficients table of the regression reveals that there is statistical significance between the price variable and sales. It is a negative correlation which implies that

previous years (EXHIBIT A). We see that 1977 and 1978 show unusually high sales. This can imply that sales do not necessarily depend on time. This is confirmed by a regression of sales in $ with time. Even though the R-squared value is not low 56.9%‚ the actual sales for 1978 does not lie in the 95% confidence interval predicted our regression (=(-7016.76 + 129.2*78 + 2(619))) (EXHIBIT B). From reading the case study‚ price seems to be a big factor determining sales. The Brazil frost disaster that
