Create a simple question about demand for an imaginary product, such as a dog-walking service. While you should not focus on how to write a good survey question in this discussion, you learn that writing and testing the question is a science in itself. For now, write the question in such a way that you may determine which of four price ranges customers would be willing to pay. After asking a few friends and family to answer the question, create a table in Microsoft® Excel showing the possible answers and how many people selected each answer. Graph the information using a histogram and a scatter plot in Excel as well. How does seeing the information in a graphical format provide more information?
What sample size would be needed to estimate the true proportion of students at your college
A committee of three is selected at random from a set consisting of five Democrats, eight Republicans, and two Independents.
Find out the sample size raised by mean also standard deviation, a sampling distribution may approach among which of the following values.
Hypothesis test for the difference between two means - To make the data comparable, certain features, such as the deductible amount and limits of liability, are standardized.
Given this, compute the following probabilities for demand during lead time(DDLT).
The critical value of F at 95% confidence when there is a sample size of 21 for the sample with the smaller variance, and there is a sample size of 9 for the sample with the larger sample variance is:
Mean=63.6 Standard deviation=2.5 If 36 data points are arbitrarily chosen, determine the probability that mean is less than 64.
If a time series is stationary without a linear trend or the seasonal component, which of the following forecasting methods may be suitable.
As part of this trial, they want to find out whether there is a difference between effectiveness for women and for men. At = .05, what is the test value?
Using the empirical rule what percentage of adults is 25 - 45 has iq score bet 70 and 130.
Test the hypothesis that the dogs did significantly better than what would be expected with random guessing.
Draw and label distribution used and position of values found.
