You are going to create your own problem from the topics that were covered from the material for that chapter. You can make the problem similar to questions from the textbook, homework, or notes. DO NOT COPY AN EXAMPLE WITH THE SAME NUMBERS. THAT IS CHEATING Create your problem:Researchers announced that 20% of all Italians living in Italy drive Americancars. A random sur vey was conducted to 100 Italians with cars, and it was foundthat 40 out of 100 have an American car. Is there enough evidence at the 5%level that 20% or more of Italians have American cars?Step #1 Hypothesize:List what is given:p=0.20 p=40/100= 0.40 n=100 x = 0.05List your Ho and Ha:Ho: p= 0.20 The portion of Italians with a car which is an American car is 20%.Hai p>0.20 The portion of Italians with a car which is an Amcrican car is greater than 20%.Step #2 Check the conditions:Condition 1: Random and independent → Randomis stated in the problem.Condition 2: Large sample rule→The population is at least 10 times as large as the sample.> 10(samplc size)All Italians living in Italy > 10(100)=1,000Condition 3: Big population rule n-PZIOΒρationn(l-p)Z 10100(1-0-20) ZIO100 (0.20) ZIO20 Z10 ♡80 Z 10 VStep #3 Find the SE and Z-Score :SE= 0.20(1-0.20) = 0.04100Z= ê-R.SEZ=040-0.200.04=5Test statistics: Z=5 Create your problem:Draw a picture of the situation with the z score then use z table to determine theprobability.NORMAL FLOAT AUTO REAL RADIAN MP100- 99.990.01%1-Prop2Test2=5p=0Write your p-value in a sentence: There is a 0.01% chance that Ho is truc.Compare the p-value to the significant level: X = 0.05Step #4 Inter pret:We rcject Ho.
