Home Security Systems:In 2008, 17% of U.S. homes were protected by a home securitysystem.A random sample of 220 homes across several neighborhoods indicated that 28% were protected.At=0.05

=

0.05

is there sufficient evidence to conclude that the proportion is actually greater?

Perform a hypothesis test using the 5-step process:

a)State Ho and H1 in symbols and in words.Then identify which hypothesis is the claim, and determine the type of test (right-tail, left-tail, two-tail).

b)Determine the critical value and label it --for example z = 1.96 or t = 2.412, etc.

c)Compute the test value.If you are using the p-value method, then include the p-value of the test.

d)Make the decision to Reject Ho or DO not reject Ho.

e)State your complete conclusion in the context of the claim.
