5. Suppose that researchers study a sample of 50 people and find
that 10 are left-handed. (a) Find a 95% confidence interval for the
population proportion that is left-handed.
(b) What would the confidence interval be if the researchers
used the Wilson value p ̃ instead?
(c) Suppose that an investigator tests the null hypothesis that
the population proportion is 18% against the alternative that it is
less than that. If α = 0.05 then find the critical value pˆc....

A 50-gram mass is hanging from a spring whose unstretched
length is 10 cm and whose spring constant is 2.5 N/m. In the list
below are described five situations. In some of the situations, the
mass is at rest and remains at rest. In other situations, at the
instant described, the mass is in the middle of an oscillation
initiated by a person pulling the mass downward 5 cm from its
equilibrium position and releasing it. Ignore both air resistance...
