High-powered experimental engines are being developed by the Hendrix Motor Company for use in their new sports coupe. The engineers have calculated the maximumhorsepower for the engines to be 620 HP. Sixteen engines are randomly selected for testing. Perform a hypothesis test to determine whether the data suggests that theaverage maximum horsepower for the experimental engine is significantly different than the maximum horsepower calculated by the engineers. Assume the data arenormally distributed and use a significance level of 0.05.Copy DataMaximum Horsepower (HP)663657641591581602666601576645594575575591597574Step 2 of 3: Compute the value of the test statistic. Round your answer to three decimal places.

A study compared grade point averages (GPA) for students in a class: students were divided by 6 locations where they usually sat during lecture (i.e. left or right front, left or right center, left or right rear). A total sample size of 12 students was studied (2 students from each section) using one-way analysis of variance. i. The sum of squared errors is SSE = 50. What is the value of the Mean Square Error (MSE )? 08.33 04.17 ONone of these O10.00 ii. The sum of squares for location is SSX= 60. What is the Mean Square for X(MSX )? O12 O10 O30 ONone of these
The Drell Yan process is the production of charged lepton pairs in hadron-hadron collisions, It takes place when a quark from one hadron and an anti-quark from another hadron annihilate to produce a sinigle virtual photon, which subsequently produces a pair of oppositely charged leptons. Estimate the ratio of the Drell-Yan cross-sections o(w*n -u")/o(x*p-+u*). Choose 1 option.
senior accounting major at Midsouth State University has job offers from four CPA firms. To explore the offers further, she asked a sample of recent trainees how many months each worked for the firm before receiving a raise in salary. The sample information is submitted to Minitab with the following results: Analysis of Variance Source df SS MS F P Factor 3 28.17 9.39 5.37 0.010 Error 15 26.26 1.75 Total 18 54.43 What is the decision rule? (Round your answer to 2 decimal places.) At the 0.05 level of significance, is there a difference in the mean number of months before a raise was granted among the four CPA firms?
Consider a data set with 15 observations and consider a multiple linear regression model with 7 in-dependent variables. Assume you have estimated the model and you find that SST = 1,325 and SSR = 794.
Suppose we have sample data on (y,x) of size n. Consider regressing y on x and a constant using the least square method (OLS estimation). The estimated equation is y = 2.59 +5.19 x + e where e is the residual. The standard errors for the constant and the coefficient were 0.51 and 1.58 respectively. To test the null hypothesis of zero coefficient (for x) at a given significance level, we may use t-statistic. Compute the t-statistic for the coefficient. Make sure the answer is round up to the nearest hundredth. e.g. 3.015 --> 3.02

Sir Francis Galton, a cousin of James Darwin, examined the relationship between the height of children and their parents towards the end of the 19th century. It is from this study that the name "regression" originated. You decide to update his findings by collecting data from 110 college students, and estimate the following relationship: Studen th = 19.6 + 0.73 × Midparh, R2 = 0.45, SER = 2.0 (7.2) (0.10) where Studenth is the height of students in inches, and Midparh is the average of the parental heights. Values in parentheses are heteroskedasticity robust standard errors. Interpret the estimated slope coefficient and intercept coefficient. What is the meaning of the regression R2 ? What is the prediction for the height of a child whose parents have an average height of 70.06 inches? a. b. с. d. What is the interpretation of the SER here? Is the slope coefficient statistically significantly different from zero (at the 5% significance level)? e.
A producer of outdoor clothing used a focus group to obtain information about the demand for fleece jackets with built-in battery operated warming panels. At prices of $100, $90, $80, $70, $60, and $50, the focus group demanded 23, 31, 40, 44, 48, and 60 jackets, respectively. Use the Excel trendline option to estimate a linear demand function and to determine the associated R² statistic. (Hint: Using Excel's scatterplot with trendline functionality, list price in the first column and quantity in the second column. Price will appear on the horizontal axis in this case.) The linear demand function is -0-0 p. (Enter your responses rounded to two decimal places.)
1. A study published in 1993 used US state panel data to investigate the relationshipbetween minimum wage and the employment of teenagers. The sample period was1977 to 1989 for all 50 states. The author estimated a model of the following type:ln(Eit) = β0 + β1ln(Mit/Wit) + γ2D2i + ... + γnD50i + δ2B2t + ... + δTB13t + uitwhere E is the employment to population ratio of teenagers, M is the nominalminimum wage, and W is average hourly earnings in manufacturing. In addition,other explanatory variables, such as the adult unemployment rate, the teenagepopulation share, and the teenage enrollment rate in school, were included.(a) Name some of the factors that might be picked up by time and state fixedeffects(b) The author decided to use eight regional dummy variables instead of the 49state dummy variables.
