- What is meant by the sample space of an experiment?What is a sample space?A researcher wanted to explore whether fish abundance in tropical coral reef systems differed significantly between the cyclone and non-cyclone seasons. To conduct this experiment, underwater visual census surveys to count the number of fish present were conducted at twenty different coral reef systems during both the cyclone and non-cyclone season of a given year. What type of statistical test should be used to determine if there is a difference in seasonal fish abundance; ANOVA, paired t-test, 1 sample t-test, or a 2 sample t-test?

Which of these two sample sizes would you recommend? Explain.Chicken farming is a multi-billion dollar industry, and any methods that increase the growth rate of young chicks can reduce consumer costs while increasing company profits, possibly by millions of dollars. An experiment was conducted to measure and compare the effectiveness of various feed supplements on the growth rate of chickens. Newly hatched chicks were randomly allocated into six groups, and each group was given a different feed supplement. Below are some summary statistics from this data set showing the distribution of weights by feed type. Mean SD Sample Size casein 323.58 64.43 12 horsebean 160.20 38.63 10 linseed 218.75 52.24 12 meatmeal 276.91 64.90 11 soybean 246.43 54.13 14 sunflower 328.92 48.84 12 (a) Do these data provide strong evidence that the average weights of chickens that were fed lineseed and horsebean are different?
