On average, the results of a stamina test after a training regimen are either poorer or equal to the results before the training regimen. True or FalseThe hypothesis below is a directional (one-tailed) hypothesis. On average, the results of a stamina test after a training regimen are either poorer or equal to the results before the training regimen. True or FalseWhich of the following formulas depicts the hypothesis below? On average, the results of a stamina test after a training regimen are either poorer or equal to the results before the training regimen.

Question 5: In project planning and management, one of the main goals of the project owner is to enhance the quality of envisaged project in domestic market through streamlined business processes and productivity. This in turn supports the overall goal of promoting a globally competitive and innovative project benefiting a given country equitably. Therefore, quality of the project is considered with the determinants of average price, project capital, income of the employees, corruption, and managerial performance index in order to identify the driving forces of competitiveness. Given the data you are given, answer the following questions. a) Compute coefficients of the regression equation of competitiveness and present in the following form:b) Compute and interpret the coefficient of determination using 5% level of significance.c) Test the level of significance and interpret all coefficients of the model at 5% level of significanced) Test whether there are problems of heteroskedasticity, autocorrelation and multicollinearity. If there are, how can you have a model without such problems?e) Which variables are policy variables and write policy prescription about the project competitiveness.

Provided below are the sizes of 15 farms, in acres, randomly selected from the state of Oregon. The mean of this sample is 483 acres.2560530341456389365193138216214440285407341370a. Find the median of the sample and compare it to the mean and discuss thedifference.b. Find the mean and the median if you throw out the 2560 acre farm which hasthe largest area by far. What does this tell you?

This is a skill-building problem 2 from Book Practical Management Science 4th Edition Winston W., Albright S. Please give me a step by step MS excel solution with constraints tutors it can be solved using Solver and SolverTable.Course hero Link to this problem is this but it does not have MS Excel step by step or constraints not even rows and columns of the solved workbook sheet https://www..com/tutors-problems/Statistics-and-Probability/26983839-Chapter-16-Gotham-City-must-determine-how-to-allocate-ambulances-duri/?justUnlocked=1(Chapter 16) Gotham City must determine how to allocate ambulances during the next year. It costs\$5000 per year to run an ambulance. Each ambulance must be assigned to one of two districts. Let xi bethe number of ambulances assigned to district i, i = 1; 2. The average time (in minutes) it takes for anambulance to respond to a call from district 1 is 40 – 3×1; for district 2, the time is 50 – 4×2. GothamCity has three goals (listed in order of priority):Goal 1: At most \$100; 000 per year should be spent on ambulance service.Goal 2: Average response time in district 1 should be at most 5 minutes.Goal 3: Average response time in district 2 should be at most five minutes.a. Use goal programming to determine how many ambulances to assign to each district.b. How does your answer change if Goal 2 has the highest priority, then Goal 3, and then Goal 1?

A television station claims that the amount of advertising per hour of broadcast time has an average of 17 minutes
A television station claims that the amount of advertising per hour of broadcast time has an average of 17 minutes and a standard deviation equal to 2.8 minutes. You watch the station for 1 hour, at a randomly selected time, and carefully observe that the amount of advertising time is equal to 14 minutes. Calculate the z-score for this amount of advertising time
Consider a study that administers either 1 mg, 1.5 mg, or 2 mg of a drug to the experimental group
Consider a study that administers either 1 mg, 1.5 mg, or 2 mg of a drug to the experimental group and measures some medical output. Under what further circumstances would a fixed effect model be appropriate? Under what further circumstances would a random effects model be appropriate?Submit your R code and any output of the code to include tables and graphs as indicated.Information about fixed vs random: In modeling, it is helpful to frame a variable as either fixed or random. A fixed variable is something like the dosage of a drug in an experiment designed to test how effective that dosage is; it is fixed because data is collected on all possible levels of the dosage, and there is no measurement error. A random variable is something like the level of abstractness of a painting, in which 1 is low, 2 is medium, and 3 is high. It is random because one would want to extrapolate the variable “abstractness” to other values of just 1, 2, and 3 for all pieces of art, and so the values 1, 2, and 3 represent a random sample of all possible other values that the variable abstractness can take on.
