In the accompanying graph, is the slope of curve AA' positive or negative? Does the slope increase or decrease as we move along the curve from A to A'? Answer the same two questions for curve BB' B

Mark Gershon, owner of a musical instrument distributorship, thinks that demand for guitars may be related to the number of television appearances by the popular group Maroon 5 during the previous month. Gershon has collected the data shown in the following table: Maroon 5 TV Appearances Demand for Guitars This exercise contains only part a. a) Graph these data using the point drawing tool. The plotted graph shows a pattern that can be described by: A. Seasonality C. Random variations 3 5 8 7 7 79 3 5 6 6 10 7 B. Trend O D. Cycles 12- 11- 10- 9- 8- 7- 6- 5- 4- 3- 2- 1- 0- Guitar Demand 4 TV Appearances -00 10 11

Can you do a IS and LM both shifting to the left a graph

a) direct relationship.  b) inverse relationship.  c) converse relationship  d) negative relationship.

Find an equation in point-slope y -y, = m(x-x,) for the line through the given points. (- 3, – 3) and (2,7) What is the equation of the line in point-slope form? (Use integers or simplified fractions for any numbers in the equation.)

In economics, what does the term ceteris paribus mean when analyzing the relationship between two variables? A. All other things being equal or held constant B. The direct relationship between two variables C. The inverse relationship between two variables D. The absence of any relationship between two variables

For each of the following scenarios, indicate whether the relationship between the two variables is positive or negative, as well as which line on the previous graph has a slope that reflects this type of relationship.   Hint: The X-axis and Y-axis on the graph are not labeled intentionally. You need to substitute the variables from each scenario for the horizontal and vertical axis. For example, in the first scenario, X-axis should be labeled “ ice-cream" and Y-axis should be labeled "The temperature". Relationship options: positive, negative Line options: A, B, C, D   True or False: Line D has a slope of infinity.

Graph and label as either direct or indirect the relationships you would expect to find between (a) the number of inches of rainfal per month and the sale of umbrellas, (b) the amount of tuition and the level of enrollment at a university, and (c) the popularity of an entertainer and the price of her concert tickets.

Use a software of your own choice to calculate the daily log prices (lp) and daily log returns (Ir) i. Examine the descriptive statistics of both lp and Ir. What do you conclude about the distributions of lp and Ir? Is lp normally distributed? Is Ir normally distributed? Obtain the correlograms, and examine the autocorrelations and partial autocorrelations for both lp and Ir. What do you conclude about the behaviour of lp and Ir? Are they stationary/non-stationary? ii. iii. Are your conclusions about stationary/non-stationary of lp and lr confirmed by appropriate unit root tests?

Given the following data table: X Y 21 68 72 55 38 59 57 57 45 61   What is the correlation between X and Y? Include 3 decimal places in your answer.
