Is this a one or two way ANOVA or should I just use a z-test to solve?
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
In a survey of the 3000 boy scouts in the National Capital Area Council (NCAC), it is found that they have a mean weight of 135 lbs with a standard deviation of 15 lbs. How many of the boy scouts have weights between 120 lbs and 150 lbs.?
State the statistical assumptions of this test Using the data set you have selected, select independent and dependent variables.
Compute the mean of the sampling distribution? Compute the standard deviation of sampling distribution?
Suppose n progeny are to be examined, and let P^ be the sample proportion of purple-owered plants. It might happen, by chance, P^ that would be closer to 1/2 than to 9/16. Find the probability that this misleading event would occur if:
A random variable is normally distributed with a mean of 25 and a standard deviation of 5. If an observation is randomly selected from the distribution:
Develop a 99 percent confidence interval for the population proportion.
Assume that demand for the upcoming weekend is normally distributed with a standard deviation of 30.
A set of 50 data values has a mean of 15 and a variance of 25. Find the standard score of a data value = 30.
