Question

2. Researchers were curious if bees near the mountains were carrying less pollen than bees near a major river. Researchers collected data on 200 bees near the Rio Grande and found 43% were carrying pollen. The estimated bee population size near the Rio Grande river is approximately a million bees. 200 bees near the Sandias were also collected and researchers found 22% were carrying pollenThe bee population near the Sandias is approximately half a million bees. Both samples were randomly collected and were independent proportion z-test statistic (Section 8.4 in the book) to determine if the proportion of bees with pollen near the Rio Grande is significantly greater than the proportion of bees with pollen near the Sandias at the 5% significance level. 1) Designate which population is pi and which is p2. State the hypotheses in words and symbols. 2) Confirm the Central Limit Theorem applies bytesting your conditions. 3) Set your significance level. 4) Determine the standard error (SE). . Use a two 5) Perform the two-proportion z-test. 6) Decide whether to reject the null or not based on your results. (Data for this homework is fictional.)
