Can you provide an example using your own data set (two related and unrelated variables) of at least twenty numbers each and apply the formula of correlation. Determine the correlation of each of the two sets of data.
Then answer whether the correlation is positive or negative? Then can you tell me what does that mean. Also can you explain the difference between a positive and a negative correlation and how the results compare the two types of data, because I'm lost, so Layman's terms please.
Simulate the arrival of cars at the service station for 20 arrivals and compute the average time between stations and Simulate the arrival of the cars at the service station for 1 hour
Machine which fills quart milk cartons is set up to average 32.2 oz per carton, with standard deviation of 1.2 oz. Determine probability that filled carton will contain less than 32 oz of milk?
In a one-way ANOVA analysis of 3 treatments, with the total number of 9 observations, with an equal number of observations in each treatment, mean-square-error (MSE) was found to be 24.905.
Perform the five-step hypothesis test on the data. - LORA - this is the portion I am responsible for based on using the nonparametric hypothesis testing.
In healthy adults, x is approximately normally distributed with mean µ = 38 and standard deviation σ = 12. What is the probability that:
Find out the conditional probability for the given data. Illustrate what is the conditional chance that the selected person is male?
An advantage of the permutation test over the t test for a difference in means, can Permutation tests be used for tests when we believe the two populations differ under the null hypothesis.
Set up a null and alternative hypothesis to test whether this sample is falling below expectations.
Develop four probability questions using the table that you as an instructor of statistics might ask a class of students for a test in probability.
An experiment involves rolling a fair six-sided die repeatedly. How many times must the die be rolled for a {6} to result at least once with probability greater than or equal to 0.6 ?
University of Waterloo are much susceptible to hypnosis which University of Tennessee undergraduates. Set up H0 and Ha for the test.
They hope to use a sample size such that, with probability 0.95, the error will not exceed 0.04. What sample size will ensure this, regardless of what sample proportion value occurs when they gather the sample?
