Question 21 SEAGULLS A biologist studying seagulls estimates that \( 5 \% \) of the seagulls in a flock have been banded. If 22 of the seagulls have been banded, approximately how many seagulls are in the flock? \( \begin{array}{ll}\text { A) } 110 \\ \text { B) } 440 \\ \text { C) } 1100 \\ \text { D) } 4400\end{array} \)

It is appropriate to model nonlinear relationships using correlational analysis. A) True (B) False

Use the sample data and confidence level given below to complete parts (a) through (d). A drug is used to help prevent blood clots in certain patients. In clinical trials, among 4140 patients treated with the drug, 137 developed the adverse reaction of nausea. Construct a \( 90 \% \) confidence interval for the proportion of adverse reactions. a) Find the best point estimate of the population proportion p. (Round to three decimal places as needed.)

The bivariate hypothesis-testing procedure that is used when both the independent and dependent variables are continuous is (A) Continuous hypothesis test (B) Pearson's correlation (C) Analysis of variance (D) continuous samples t-test

Exercise 1. How many residents had at least two falls in the last 24 months? Put the answer in cell B15. Exercise 2. What percentage of the nursing home residents had at most eight falls in the last 24 months? Put the answer in cell B16.
