P: Parameter What is the correct parameter symbol and wording for population 1? the mean length of 29 randomly selected New Zealand rivers that flow into the Pacific Ocean w What is the correct parameter symbol and wording for population 2? X, V = the mean length of all New Zealand rivers that flow into the Tasman Sea H: Hypotheses Ho: P. - P. V ? v km HA: n, -n, v ? y km A: Assumptions Since quantitative information was collected from each object, we need to check the following conditions: Check all that apply. Ox1 > 10 and 12 2 10 On - $1 2 10 and n2 - 12 2 10 On 2 20n, and n2 2 20n2 O The samples are independent The samples are dependent O Normal population of differences or at least 30 pairs of data Normal populations or n1 2 30 and n2 2 30 O no outliers in the differences O no outliers for each group O o is unknown for each group Do is known for each groupThe 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? a) Test at the 5% level. b) Compute a 90% confidence interval for the difference.
