A new experimental drug has been approved to be tested as a treatment for Parkinson's Disease (PD). I dopa has traditionally been the drug treatment of choice in treating PD. Researchers are interested in whether the new experimental drug will improve symptoms of PD to a greater extent than L-dopa.

A) State the null and research hypotheses

b) Is this a non-directional or a directional hypothesis? How do you know?

c) The hypothetical results indicate that the new experimental drug improved
symptom. Give a conclusion.

D) The hypothetical results indicate that the new experimental drug did not improve symptoms. Give a conclusion

Evaluate 8x2 + 9x − 1 2x3 + 3x2 − 2x dx. solution since the degree of the numerator is less than the degree of the denominator, we don't need to divide. we factor the denominator as 2x3 + 3x2 − 2x = x(2x2 + 3x − 2) = x(2x − 1)(x + 2). since the denominator has three distinct linear factors, the partial fraction decomposition of the integrand has the form† 8x2 + 9x − 1 x(2x − 1)(x + 2) = correct: your answer is correct. to determine the values of a, b, and c, we multiply both sides of this equation by the product of the denominators, x(2x − 1)(x + 2), obtaining 8x2 + 9x − 1 = a correct: your answer is correct. (x + 2) + bx(x + 2) + cx(2x − 1).
