Consumer math question
Question #1 – Simple InterestJack borrowed money to finance his new business. Private investors offered Jack $28,000 of the $35,000 he needed. To make up the difference, Jack secured a small business, simple interest loan. Jack’s loan was structured as an installment loan and required him to pay $297.50/month for 30 months. Calculate the amount financed, total installment price, the finance charge, and the interest rate.The calculations on how each answer was reached must be provided!!!

I need help with my Inferential Statistics Class it is kicking my butt
CompetencyFormulate and evaluate hypothesis tests for population parameters based on sample statistics using both Critical Regions and P-Values, and be able to state results in a non-technical way that can be understood by consumers of the data instead of statisticians.Student ProfileYou are a statistician working for a drug company. A few new scientists have been hired by your company. They are experts in pharmacology, but are not experts in doing statistical studies, so you will explain to them how statistical studies are done when testing two samples for the effectiveness of a new drug. The two samples can be dependent or independent, and you will explain the difference.
Concept being Studied Your focus is on hypothesis tests and confidence intervals for two populations using two samples, some of which are independent and some of which are dependent. These concepts are an extension of hypothesis testing and confidence intervals which use statistics from one sample to make conclusions about population parameters.What to SubmitYour research and analysis should be presented on the Word document provided. All calculations should be provided on a separate Excel workbook that should be submitted to your boss as well.

*** You can use any statis tic software to solve (SPSS, Eviews, R...)*** The result of each problem must contain RESULT TABLE (from the software) and EXPLANATION (Short or long)*** The data file is in .xls form (Excel needed)Background A good understanding of the macroeconomic cycle with alternating recession and expansion periods (also known as the business cycle) is important for various decision makers. Macroeconomic policy is often based on predictions of this cycle, and such predictions can influence investment decisions of large companies. Central banks and other institutions often publish so-called leading indicators that are helpful to predict the state of the economy. These indicators are based on macroeconomic series like job formation, interest rates, credit, demand, and supply. In this case project you will predict GDP growth by using quarterly data on a hypothetical economy from 1950 quarter 1 to 2015 quarter 4. The data set contains the GDP of the economy and two leading indicators li1 and li2. In order to evaluate the predictive performance of econometric models, you need to split the data in two parts. As estimation sample you take the period from 1951 to 2010 (240 observations), and as evaluation sample you take the period from 2011 to 2015 (20 observations). The first year of data (1950) is used only to create lags of variables. The project consists of two parts. In the first part (a-c) you use logit models to predict whether the economic situation improves or declines, and in the second part (d-g) you use time series models to predict the size of the growth rate of the economy.Data The data file Case GDP contains the following variables: • DATE: Date of the observation; • GDP: Gross Domestic Product of the economy; • GDPIMPR: dummy variable indicating whether the GDP has increased (1) or decreased (0); • LOGGDP: Log of Gross Domestic Product; • GrowthRate: Relative growth of the economy: GrowthRatet = log(GDPt ) − log(GDPt−1); • li1: First leading indicator; • li2: Second leading indicator; • T: Linear trend (where the first observation, for 1950 quarter 1, is defined as 0).(a) The table below summarizes the outcomes of four logit models to explain the direction of economic development (GDPIMPR) for the period 1951 to 2010. Perform three Likelihood Ratio tests to prove both the individual and the joint significance of the 1-quarter lags of li1 and li2, where the alternative hypothesis is always the model with both indicators included. (Please see image name TABLE 1)b) It could be that the leading indicators lead the economy by more than 1 quarter. The table below summarizes outcomes of four logit models that differ in the lags of the indicators. For what reason can we use McFadden R2 to select the best lag structure among these four models? Compute the four values of McFadden R2 (with four decimals) and conclude which model is optimal according to this criterion. (Please see image name TABLE 2)(c) Use the logit model 3 of part (b) (with li1(-2) and li2(-1)) to calculate the predicted probability of economic growth for each of the 20 quarters of the evaluation sample. Assess the predictive performance by means of the prediction-realization table and the hit rate, using a cut-off value of 0.5. Evaluate the outcomes.(d) Perform the Augmented Dickey-Fuller test on LOGGDP to confirm that this variable is not stationary. Use only the data in the estimation sample and include constant, trend, and a single lag in the test equation (L = 1, see Lecture 6.4). Present the coefficients of the test regression and the relevant test statistic, and state your conclusion.(e) Consider the following model: GrowthRatet = α + ρGrowthRatet−1 + β1li1t−k1 + β2li2t−k2 + εt . Here the numbers k1 and k2 denote the lag orders of the leading indicators. Estimate four versions of this model on the estimation sample from 1951 to 2010, by setting k1 and k2 equal to either 1 or 2. Show that the model with k1 = k2 = 1 gives the largest value for R2, and present the four coefficients of this model in six decimals. (f) Perform the Breusch-Godfrey test for first-order residual serial correlation for the model in part (e) with k1 = k2 = 1. Does the test outcome signal misspecification of the model?(g) Use the model in part (e) with k1 = k2 = 1 to generate a set of twenty one-step-ahead predictions for the growth rates in each quarter of the period 2011 to 2015. Note that the required values of the lagged leading indicators are available for each of these forecasts. Calculate the root mean squared error of these forecasts and present a time series graph of the predictions and the actual growth rates.
