Suppose studies have shown that the ideal amount of Potassium in the soil for

growing almonds is 54 units. A random sample of 71 soil readings from a potential almond

orchard has a sample mean of 52.8 and a sample standard deviation of 8.2. Is the population

mean Potassium level in the soil for the potential orchard different from 54? Conduct a

hypothesis test using α=.01. Show your work

1. Numerous studies have shown that IQ scores have been increasing, generation by generation, for years. The increase is called the Flynn Effect, and the data indicate that the increase appears to be about 7 points per decade. To demonstrate this phenomenon, a researcher obtains an IQ test that was written in 1980. At the time the test was prepared, it was standardized to produce a population mean of µ = 100 and σ = 15. The researcher administers the...

7. Measures of effect size for the repeated-measures t Previous studies have shown that playing video games can increase visual perception abilities on tasks presented in the gaming zone of the screen (within 5 degrees of the center). A graduate student is interested in whether playing video games increases peripheral visual perception abilities or decreases attention to peripheral regions because of focus on the gaming zone. For his study, he selects a random sample of 64 adults. The subjects complete...

Suppose a growing health and wellness company is rolling out three new nutritional diet plans. The research department wants to test the effectiveness of these three new nutritional plans, a low-fat plan and a low-carb plan, as well as its standard low-calorie plan. Marcia, a nutrition researcher with the company, randomly assigns 24 new weight loss program participants to each of the three plans, assigning 8 to each plan. After administering the plans, she follows up with the participants a...

From previous studies, it has been generally believed that Northern Hemisphere icebergs have a mean depth of 270 meters. An environmentalist has suggested that global warming has caused icebergs to have greater depth. A team of scientists visiting the Northern Hemisphere observed a random sample of 41 icebergs. The depth of the base of the iceberg below the surface was carefully measured for each. The sample mean and standard deviation were calculated to be 276 meters and 20 meters respectively....

MTH 241 COMMON DATA ANALYSIS ASSIGNMENT (Fall 2018) Previous studies have shown that urban bus drivers have an extremely stressful job, and a large proportion of drivers retire prematurely with disabilities due to occupational stress. These stresses come from a combination of physical and social sources such as traffic congestion, incessant time pressure, and unruly passengers. In the paper, “Hassles on the Job: A Study of a Job Intervention with Urban Bus Drivers” (Journal of Organizational Behavior, Vol. 20, pp....
