Question

In a certain​ survey,

51

people chose to respond to this​ question: "Should passwords be replaced with biometric security​ (fingerprints, etc)?" Among the​ respondents,

55%

said​ "yes." We want to test the claim that more than half of the population believes that passwords should be replaced with biometric security. Complete parts​ (a) through​ (d) below.

 

Are any of the three requirements​ violated? Can a test about a population proportion using the normal approximation method be​ used?

It was stated that we can easily remember how to interpret​ P-values with​ this: "If the P is​ low, the null must​ go." What does this​ mean?
 
Another memory trick commonly used is​ this: "If the P is​ high, the null will​ fly." Given that a hypothesis test never results in a conclusion of proving or supporting a null​ hypothesis, how is this memory trick​ misleading?
 
Common significance levels are 0.01 and 0.05. Why would it be unwise to use a significance level with a number like​ 0.0483?
