Classify the experiments according to their experimental designs. Some designs may be used more than once.
A New York Times article titled For Runners, Soft Ground Can Be Hard on the Body considered two
perspectives on whether runners should stick to hard surfaces or soft surfaces following an injury. One
position supported running on soft surfaces to relieve joints that were in recovery from injury. The
second position supported running on hard surfaces since soft surfaces can be uneven, which may make
worse those injuries a soft surface was intended to help.
Suppose we are given sufficient funds to run an experiment to study this topic. With no studies to
support either position, which of the following hypotheses would be appropriate?
The first position is more sensible, so this should be a one-sided test. In this case, we should form
the alternative hypothesis around the second position.
The second position makes the more sense, so this should be a one-sided test. In this case, we
should form the alternative hypothesis around the first position.
Because we would be interested in any…

Suppose we are given sufficient funds to run an experiment to study this topic. With no studies to support either position, which of the following hypotheses would be appropriate?
1. The second position makes the more sense, so this should be a one-sided test. In this case, we should form the alternative hypothesis around the first position.
2. Because we would be interested in any difference between running on hard and soft surfaces, we should use a two-sided hypothesis test.
3. Because there is uncertainty, we should postpone…

Some shrubs can resprout from their roots after their tops are destroyed. One study of resprouting took place in a dry area of Mexico. The investigators first clipped the tops of all the shrubs in the study. For the treatment, they then applied a propane torch to the stumps of the shrubs to simulate a fire, and for the control the stumps were left alone. The study included 24 shrubs of which 12 were randomly assigned to the treatment and the remaining 12 to the control. A shrub is a success if it resprouts. For the shrub Xerospirea hartwegiana, all 12 shrubs in the control group resprouted, whereas only 8 in the treatment group resprouted. How much does burning reduce the proportion of shrubs of this species that resprout? Give the 95% plus four confidence interval for the amount by which burning reduces the proportion of shrubs of this species that resprout. The plus four method is particularly helpful…arrow_forward

How can you tell?arrow_forwardYou want to find out whether caffeine mitigates the effect of alcohol on reaction time. To study this, you administer to your subjects a drink that is equivalent to three 12-ounce beers, followed by the equivalent of two cups of coffee. Then your subjects complete a simulated driving task in which they must follow a fixed speed limit while driving on a straight road. Wind periodically and randomly pushes the simulated vehicle right, left, or not at all. Speed is measured in miles per hour above or below the 60-mph speed limit, with 1 mph being the smallest unit on the scale. Suppose the first subject scores 5 mph. Determine the real limits of 5. 1)The lower real limit is: 2)The upper real limit is: When measuring weight on a scale that is accurate to the nearest 0.1 pound, what are the real limits for the weight of 120 pounds? a)119.75–120.25 b)120–121 c)119.95–120.05 When measuring weight on a scale that is accurate to the nearest…arrow_forwardCould you help me with this, please? & could you provide more details for me? thank you so much! One general belief held by observers of the business world is that taller men earn more money than shorter men.

These responses are recorded in MBA.xlsx. d Obtain three measures to check the fitness of the model. Do you think that this model is good enough to be used to estimate and predict income on the basis of height? If not, explain why not. If so, i predict the income of 183cm tall men with MBAs. ii estimate with 95% confidence the mean income of all 183 cm tall men with MBAs iii predict with 95% confidence the income of a 183 cm tall man with an MBA.

- Par, Inc., is a major manufacturer of golf equipment. Management believes that Par's market share could be increased with the introduction of a cut-resistant,longer-lasting golf ball. Therefore, the research group at Par has been investigating a new golf ball coating designed to resist cuts and provide a more durable ball. The tests with the coating have been promising. One of the researchers voiced concern about the effect of the new coating on driving distances. Par would like the new cut-resistant ball to offer driving distances comparable to those of the current-model golf ball. To compare the driving distances for the two balls,40 balls of both the new and current models were subjected to distance tests. The testing was performed with a mechanical hitting machine so that any difference between the mean distances for the two models could be attributed to a difference in the two models. The results of the tests, with distances measured to the nearest yard, follow. These data are…arrow_forwardPar, Inc., is a major manufacturer of golf equipment.

As part of their study they have a colony of Pink-striped Oakworm moths that have been raised in a controlled environment in their labs. They have collected several pieces of data about the male Luna moths in their colony in order to determine if the pupal mass of the males was related to their rate of development. 17) Looking at the graph on Pupal Mass vs Development Time, what type of graph is this?
