Professor Tao has commissioned Ethan to investigate the population of Pokemon on Route 301. Ethan wanders around until he encounters 100 Pokemon on Route 301 (assume encountering a Pokemon is equivalent to drawing randomly from the population of Pokemon.) He catches each Pokemon he encounters and records its species: Pikachu Balbasaur Charmander Squirtle 20 19 26 35 Professor Tao thinks there should be an equal chance of finding each of the four species of Pokemon. Run a test for this hypothesis at the 1% significance level. Be sure to: a) state hypotheses (1 point) b) calculate the test statistic (2 points) c) calculate the p-value (1 point) d) draw conclusions, and interpret in context (1 point)

A scientist is comparing the mean weight of watermelons at two farms, farm A and farm B at a 5% significance level. He selected a random sample of 100 watermelons from farm A with a mean weight of 21.6 and a sample SD of 3.6 pounds. The random sample from farm B had 400 watermelons with a mean weight of 22.7 and a sample SD of 2.6 pounds.  Select the correct option in each case.  The appropriate test of significance the researcher should apply in this scenario is [color1] The appropriate standard error is [color2] The study type in this scenario is [color3]
