The 1995 version has 30 five-way multiple choice questions. Example question (question 4): A large truck collides head-on with a small compact car. During the collision: the truck exerts a greater amount of force on the car than the car exerts on the truck. the car exerts a greater amount of force on the truck than the truck exerts on the car.
This ensures that the hypothesis test maintains its specified false positive rate (provided that statistical assumptions are met). [35] The p-value is the probability that a test statistic which is at least as extreme as the one obtained would occur under the null hypothesis. At a significance level of 0.05, a fair coin would be expected to ...
Precision tests of QED have been performed in low-energy atomic physics experiments, high-energy collider experiments, and condensed matter systems. The value of α is obtained in each of these experiments by fitting an experimental measurement to a theoretical expression (including higher-order radiative corrections) that includes α as a parameter.

A Bell test, also known as Bell inequality test or Bell experiment, is a real-world physics experiment designed to test the theory of quantum mechanics in relation to Albert Einstein's concept of local realism.
The International Physics Olympiad began in 1967 among Eastern European countries; many western countries soon joined in the 1970s. In 1986, the American Association of Physics Teachers led by Jack Wilson organized the United States Physics Team for the first time. The 1986 team was made up of 20 talented high school physics students nominated ...
From the t-test, the difference between the group means is 6-2=4. From the regression, the slope is also 4 indicating that a 1-unit change in drug dose (from 0 to 1) gives a 4-unit change in mean word recall (from 2 to 6). The t-test p-value for the difference in means, and the regression p-value for the slope, are both 0.00805. The methods ...
The GRE physics test is an examination administered by the Educational Testing Service (ETS). The test attempts to determine the extent of the examinees' understanding of fundamental principles of physics and their ability to apply them to problem solving.
