The table shows the number of households burglarized in a sample of households with dogs and in a sample of households without dogs. Assume that you plan to use a significance level of ΅ = 0.01 to test the claim that p1 <p2. Find the critical value(s) for this hypothesis test. Do the data support the claim that a smaller proportion of households with pet dogs are burglarized?
   Household with dog household without dog

Number of households in sample 183    100

Number of households burglarized 25    11

A) z =2.33; yes

B) z =-2.33; no

C)z =-1.96; yes

D) z =-2.575; no

A random sample of households in Orange County showed that 11 out of 162 them were burglarized in the past 5 years. And in a random sample of households in Cook County, 25 out of 238 of them were burglarized in that same time period. We will test the claim that the proportion of Orange County households that were burglarized (p1) is not equal to the proportion of Cook County households that were burglarized (p2).

) The table shows the number of smokers in a random sample of 500 adults aged 20-24 and the number of smokers in a random sample of 450 adults aged 25-29. Assume that you plan to use a significance level of α = 0.10 to test the claim that p1 ≠ p2. Find the critical value(s) for this hypothesis test. Do the data provide sufficient evidence that the proportion of smokers in the 20 -24 age group is different from...
