- I'm working on inflation forecasting with quarterly inflation data for 1960 to 2022 using ARIMA model. The initial data is non-stationary. After the first differencing, based on the results of the p-value, it shows that the data is stationary. Then plot the ACF and PACF after first differencing, as attached pictures.With the graph of ACF and PACF, how can I define p, d, q for my ARIMA (p, d, q) model?ThankyouMethods used in the Estimation of parameters in a point EstimateRegarding a χ2-curve: a. At what point on the horizontal axis does the curve begin?b. Classify its shape as symmetric, left skewed, or right skewed.c. As the number of degrees of freedom increases, a χ2-curve begins to look like another type of curve. What type of curve is that?
- Create a scatter diagram of Y = ‘Annual % ROI’ against X = ‘Cost’. Include the trendline and the coefficient of determination right on the graph. Calculate the estimated ‘Annual % ROI’ when the ‘Cost’ (X) is $160,000. Show your work. Conduct a full hypothesis test: You will be in charge. Set your own logical significance level. State it. Claim: There is a relationship between cost and Annual %ROI. The hypotheses are given but you must also state them. Make sure all the steps of hypothesis testing are present.

Determine the critical points, points of inflection, and trace the curve.Scenario: An HR manager wants to know if there is a difference between sexes (males and females) on number of years employed at his firm. Assume the data meets assumptions for a parametric test. Question: What is the scale of measurement of the dependent variable in this scenario?
- Relative minimum/maximumOsteoporosis is a degenerative disease that primarily affects women over the age of 60. A research analyst wants to forecast sales of StrongBones, a prescription drug for treating this debilitating disease. She uses the model Sales = β0 + β1Population + β2Income + ε, where Sales refers to the sales of StrongBones (in $1,000,000s), Population is the number of women over the age of 60 (in millions), and Income is the average income of women over the age of 60 (in $1,000s). She collects data on 38 cities across the United States and obtains the following regression results: Coefficients StandardError t Stat p-Value Intercept 10.35 4.02 2.57 0.0199 Population 8.47 2.71 3.12 0.0062 Income 7.62 6.63 1.15 0.2661 a.

A study examined the radioactive cesium tissue concentration of a random sample of 16 Pacific bluefin tuna, Thunnus orientalis, captured off the coast of California four months after the Fukushima nuclear reactor meltdown of 2011. Here are the findings, (the units are in becquerels per kilogram of dry tissue.) (a) Describe the unknown parameter using the context of this study and correct symbol for this parameter.(b) Construct a 99% confidence interval to estimate this parameter.(c) Give a practical interpretation for this confidence interval, using the context of this problem.
