In some area of interest to you (not from the text), create a hypothetical experiment to resolve a claim about a population with sampling of data and a hypothesis test. Describe the claim, the experiment, the test statistic, and clearly state the null and alternative hypotheses. In fact, the outline of a good response looks like this:
I) Description of problem and statement of claim
II) Statement of null hypothesis
III) Statement of alternative hypothesis
IV) Description of experiment and sampling plan
V) Description of test statistic and the form of the actual test with critical value(s)
The interpretation of natural logarithms and common logarithms
The accounting department at Weston Materials, Inc., national manufacturer of unattached garages, reports that it takes two construction workers mean of 32 hours and standard deviation of 2 hours to erect the Red Barn model.
Find the minimum sample size needed, using a prior study that found that 19% of computers needed repairs or had problems by the time the product was three years old.
State in each of given cases whether you would expect relationship between given variables to be positive or negative or neither.
Using data provided, test if there is a difference between means at alpha =.05.
In other words, both variables have the same mean but different standard deviations. Draw rough sketches of the two normal curves on the same graph.
Standard deviation of 10 minutes. A random sample of 16 cars is selected. What is the probability that the sample mean is between 45 and 52 minutes.
When the null hypothesis is rejected in the goodness-of-fit test, it means there is close agreement between the observed and expected frequencies.
How large a sample is required to estimate the mean speed with a margin of error equal to 2 miles per hour with 90% confidence?
To find out the prior probability, conditional probability and posterior probability. Calculate the posterior probability that the bid will be successful given a request for additional information.
A trucking firm suspects that the mean lifetime of a certain tire uses is less than 35,000miles. To check the claim the firm randomly selects and tests 54 of these tires and gets a mean life time of 34,570
Given that Z is standard normal randam variable. Compute the value of Z if area between –Z and Z is 0.754:
