n 8 of 17 O Attempt 1 Suppose a biologist is studying the population of fish in freshwater lakes. He collects data on the number of different species of fish found in 20 lakes. The boxplot displays the results of the study with species of fish in intervals of 50. Create a five-number summary of the data set. Round values to the nearest 25 species. 200 250 300 350 400 450 s00 s50 600 650 700 Number of species of fish 200 min = species Q, = 300 species Incorrect 550 median = 600 species Q3 = species Incorrect Incorrect max = 700 species DELL & 7 8 y + I| く0 口 5
When a population is finite, the formula that determines the standard error of the mean needs to be adjusted. If N is the size of the population and n is the size of the sample (where n ≥ 0.05N), the standard error of the mean is shown below. The finite population correction factor is given by the expression √(N-n)/(N-1). Determine the finite population correction factor for each of the following. (a) N = 1400 and n = 1050 (b) N = 1400 and n = 140 (d) N = 1400 and n = 70 (c) N = 1400 and n = 75 (e) What happens to the finite population correction factor as the sample size n decreases but the population size N remains the same? (a) The finite population correction factor is (Round to three decimal places as needed.) (b) The finite population correction factor is (Round to three decimal places as needed.) (c) The finite population correction factor is (Round to three decimal places as needed.) (d) The finite population correction factor is (Round to three decimal places as needed.) (e)…
Let X be the number of blueberries on a muffin made by Michael, and denote by m to be its median. Charles suspects that Michael has been adding more blueberries than usual to his muffins. For some reason, he has kept meticulous records. The last 15 muffins Charles bought contained the following numbers of blueberries: 96 12 8 15 7 8 12 6 10 13 11 11 10 10 Charles would like to test Ho: m = 9 against H₁: m>9 at significance level a = 0.1. (a) Use the sign test to test the hypothesis. (b) Use the Wilcoxon sign-rank test to test the hypothesis. (Note: Assume that the distribution is continuous) (c) Use the t-test to test the hypothesis, assuming the underlying distribution is symmetric.

A chi‑square statistic (?2) from a 4×3 two-way (contingency) table is 15.15661. Determine the upper and lower limits for the range of ?-values with this chi-square table. Please use the number of decimal places shown in the table. If the value of ?2 is too large to be in the table, use 0 for the lower limit. If the value of ?2 is too small to be in the table, use 1 for the upper limit. lower limit: upper limit:
Harper collected data on students who make appointments to see their advisor to see how many failed to show up. The student records were divided into two groups: male (group 1) and female (group 2). A 93% confidnece interval for pi – P2 was found to be as follows: (0.03, 0.09) Interpret the endpoints of this interval in the context of this problem. Do not use the word "difference" in your answer.
