[T] The following problems consider the scalar form of Coulomb’s law, which describes the electrostatic force between two point charges, such as elections. It is given by the equation F ( r ) = k e | q 1 q 2 | r 2 where k e is Coulomb's constant, q i are the magnitudes of the charges of the two particles, and r is the distance between the two particles. 169. Instead of making the force 0 at R, instead we let the force be 10 − 20 for r ≥ R . Assume two protons, which have a magnitude of charge 1.6022 × 10 − 19 C , and the Coulomb constant k e = 8.988 × 10 9 N m 2 / C 2 . Is there a value R that can make this system continuous? If so, find it. Recall the discussion on spacecraft from die chapter opener. The following problems consider a rocket launch from Earth's surface. The force of gravity on the rocket is given by F ( d ) = − m k / d 2 , where m is the mass of the rocket, d is the distance of the rocket from the center of Earth, and k is a constant.

You want to determine whether or not the mean of the population from which this sample was taken is significantly different from 49. (Assume the population is normally distributed.)
(a)
State the null and the alternative hypotheses. (Enter != for ≠ as needed.)
H0:
Ha:
(b)
Determine the test statistic. (Round your answer to three decimal places.)
(c)
Determine the p-value, and at the 5% level of significance, test to determine whether or not the mean of the population is significantly different from 49.
Find the p-value. (Round your answer to four decimal places.)
p-value =
State your conclusion.
Reject H0. There is insufficient evidence to conclude that the mean of the population is different from 49.Do not reject H0. There is sufficient evidence to conclude that the…
