Homework Answers
Ans A: It must have the ability to be proven wrong by some test. The reason is that when a hypothesis is made there must be some possible negative answer for the same, meaning that one of the possible result of the experimental setup must be an answer which when obtained, can be able to disprove the hypothesis. For eg. If a person hypothesize that all birds can fly, seeing the ostrich not being able to fly will falsify the same hypothesis.

You need to interpret the results of a recent paired t-test. What does the following mean? The test statistic t-value = -1.47 and the p-value = 0.01. A.) The small p-value means there is great chance of getting data like observed here again. Because the p-value is so small, the null hypothesis cannot be rejected. This indicates the data provided enough evidence to not reject the null. The test statistic t-value of -1.47 means the data is 1.47 standard errors...

In an experiment, 17 babies were asked to watch a climber attempt to ascend a hill. On two occasions, the baby witnesses the climber fail to make the climb. Then, the baby witnesses either a helper toy push the climber up the hill, or a hinderer toy preventing the climber from making the ascent. The toys were shown to each baby in a random fashion. A second part of this experiment showed the climber approach the helper toy, which is...

ESAND ABUSES 1 Uses Hypothesis Testing Hypothesis testing is important in many different fields because it gives a scientific procedure for assessing the validity of a claim about a population. Some of the concepts in hypothesis testing are intuitive, but some are not. For instance, the American Journal of Clinical Nutrition suggests that eating dark chocolate can help prevent heart disease. A random sample of healthy volunteers were assigned to eat 3.5 ounces of dark chocolate each day for 15...

PHYSICS: Can someone help me identify a concept/hypothesis and possible experiment to run? THis is supposed to be a mock experiment and not an actual lab completed. Look around and find a certain pattern. Describe the pattern / phenomena that you have selected. Pretend that you have just performed your observation or observational experiment. You may need to repeat the observation at a later time, if there is a possibility. Illustrate it with a photo or a sketch. Devise a...

In order to estimate the mean amount of time computer users spend on the internet each month, how many computer users must be surveyed in order to be 95% confident that your sample mean is within 11 minutes of the population mean? Assume that the standard deviation of the population of monthly time spent on the internet is 200 min. What is a major obstacle to getting a good estimate of the population mean? Use technology to find the estimated...

The mean waiting time at the drive-through of a fast-food restaurant from the time an order is placed to the time the order is received is 85.2 seconds. A manager devises a new drive-through system that she believes will decrease wait time. As a test, she initiates the new system at her restaurant and measures the wait time for 10 randomly selected orders. The wait times are provided in the table to the right. Complete parts (a) and (b) below....
