You have been hired by a used car dealership in Prince George to perform a statistical analysis on the used cars that were sold from their lot in 2005 and 2008. They have provided you a list of 60 prices of the vehicles that were sold. They have also indicated whether the vehicle was sold in 2005 or 2008.
A) Prepare a histogram from the entire sample of price data. Separate the prices into $4000 intervals with the minimum being $10550 and the maximum being $26550.
B) From the histogram that you have just created, use the cutpoints as original values to code the price data into the following 4 new text groups (beginning with the cheapest group): Low, Middle, Middle-High, and High. Tally the results to determine the number of cars sold in each group. Prepare a Pie Chart (%) that will inform the dealership what percentage of the cars sold fell into each group.
C) Make some comments to explain your graph.
Using an alpha level of 0.05, please use SPSS to perform a one-way ANOVA and then determine whether the data below provide evidence for Theory A, Theory B, or Theory C. In other words, is one theory stronger than the others?
Estimating the value of the population mean on the basis of the sample mean alone produces a(n):
Are you doubtful of any of these data points? if so why does there show to be a linear relation between degree of stenosis and nuber of reactive nuclei?
The dimension is supposed to be 224 mm and the variability of the manufacturing process is unknown. Is there evidence that the mean dimension is not 224 mm?
Which of the following models satisfies the rules of probability and The event corresponding to the above system functioning properly during one period of operation is
Plan the scatter diagram
Evaluate the value of population proportion. Develop a 99% confidence interval for population proportion.
If standard deviation is 50 hours and α is equal to 0.01, what values for mean x will result in rejection of null hypothesis.
Suppose population standard deviation for those drinking regular coffee is 1.20 cups per day and 1.36 cups per day for those drinking decaffeinated coffee.
Identify the independent and dependent variables, and Construct a nominal, ordinal, and interval level measure for each independent and dependent variable.
To avoid the problem of not having access to Tables of F distribution with values given for the lower tail, the numerator of the test statistic should be the one with:
Interpret this data using regression and interpret all the findings, R 2 , F, IV coefficient, and the intercept.
