Question

*When using Binomial distribution Applet, please be as detailed as possible with what value goes where**

In 2004 Florida was hit by four major hurricanes. In 2005 a survey indicated that, in 2004, 48% of the households in Florida had no plans for escaping an approaching hurricane. Suppose that a recent random sample of 55 households was selected in Gainesville and that those in 32 of the households indicated that their household had a hurricane escape plan.

Let Y be the number of Gainesville households that have a hurricane escape plan in a sample of size 55. Use the Binomial Distribution applet to determine the minimum value of b such that P(Y ≥ b) ≤ 0.05, which would allow you to conclude that the 2004 Florida percentages do not apply to recent Gainesville households.

b =
