Question Description
I need support with this Statistics question so I can learn better.
Bert computes a 95% confidence interval for p and obtains the interval [0.600,0.700]. Note: Parts (a) and (b) are not connected: Part (b) can be answered even if one does not know how to do part (a).
(a) Bert’s boss says, “Give me a 90% confidence interval for p.” Calculate the answer for Bert.
(b) Bert’s boss says, “Give me a 95% confidence interval for p?q.” Calculate the answer for Bert. (Hint: p?q = p?(1?p) = 2p ? 1. Bert’s interval says, in part, that “p is at least 0.600;” what does this tell us about 2p ? 1?)
