A survey from March 1995 showed that very few people planned to refinance their homes during 1996. But 35% said they want to reduce (pay down) their level of debt. A random sample of 300 people was gathered and they were all asked if they planned to reduce their level of debt.

a) Find the probability that the sample proportion of people who intend to reduce their debt is less than 0.30

b) Find the probability that the sample proportion is between 0.35 and 0.45

c) Find a value x such that P(P' ≥ x) = 0.01
