Randomly selected cans of Coke are measured for the amount of cola in ounces. The sample values listed below have a mean of 12.19 ounces and a standard deviation of 0.11 ounces. Use a 0.05 significance level to test the claim that cans of coke have a mean amount of cola greater than 12 ounces.
Suppose the population standard deviations are not the same. At.05 significance level, is there a difference in mean waiting time?
Evaluate z statistic for the Wilcoxon rank sum test, standard deviation for the Wilcoxon rank sum test and P-value for the Wilcoxon rank sum test
Consider that measurement 2 (M2) in random sample of 1000 controls from the Disease Y study population follows the normal distribution.
For the following scores, find the (A) mean, (B) median, (C) sum of squared deviations, (D) variance, and (E) standard deviation:
Do the data in the sample represented in the Excel file support his contention at the .05 level of significance?
You may assume the sample data comes from a population that follows a normal distribution. Using a .05 level of significance test the company's claim.
How can you answer the dual simplex question with maximization objective function and also explain difference between m tecnique and two phase method?
Would it be reasonable to conclude that the population mean is 63 pounds?

Data is distribution of the most popular colors for 2005 model luxury cars made in North America. Design the pie chart and bar graph for data.
If two randoom samples of sizes n1 = 30 and n2 = 36 are selected independently from two populations with mean 78 and 85, and with standard deviations 12 and 15, respectively, then the standard error of the difference between Xbar1 and Xbar2 are eq..
