A: Assumptions Assume conditions are met. N: Name the test The conditions are met to use a 2-Proportion Z-Test v. T: Test Statistic The symbol and value of the random variable on this problem are as follows: Round value to 2 decimal places km Set up the formula of the test statistic with numbers rounded to 2 decimal place: $1 - 22 t = + + * 21 )) Final answer from technology to 2 decimal places: f =The length (in km) of a random sample of New Zealand (NZ) rivers that travel to the Pacific Ocean and the lengths (in km) of a random sample of New Zealand rivers that travel to the Tasman Sea are given in the table below. Do the data provide enough evidence to show on average that the rivers that travel to the Pacific Ocean are longer than the rivers that travel to the Tasman Sea? Test at the 4% level. Lengths of Rivers to Tasman Sea (in km) Lengths of Rivers to Pacific Ocean (in km) 35 64 85 209 38 171 76 72 64 188 82 64 72 140 64 122 105 163 56 66 P: Parameter What is the correct parameter symbol and wording for population 1? V= the length of a randomly selected New Zealand river that flows into the Pacific Ocean v What is the correct parameter symbol and wording for population 2?
