Suppose 205 subjects are treated with a drug that is used to treat pain and 52 of them developed nausea. Use a 0.05 significance level to test the claim that more than 20% of users develop nausea. Identify the null and alternative hypotheses for this test. Choose the correct answer below. A. $H_0: p = 0.20$ $H_1: p < 0.20$ B. $H_0: p = 0.20$ $H_1: p > 0.20$ C. $H_0: p > 0.20$ $H_1: p = 0.20$ D. $H_0: p = 0.20$ $H_1: p \neq 0.20$ Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is $\Box$. (Round to two decimal places as needed.)

1. As discussed in class multivalued functions have more than one answer. For example the square root function is multivalued (2 answers). The square root of 4 has the 2 answers +2 and -2 while the square root of -4 has the two answers +2i and -2i where i is the root of -1. Some roots are purely real numbers like 2 or may be purely imaginary numbers like 2i. Some roots are complex numbers which have both a real and an imaginary part like (a+bi) where a and b are real numbers. Cubed roots have 3 answers. For example one cubed root of 8 is +2 ($2^3 = 8$). Verity that (-1+i\sqrt{3}) and (-1-i\sqrt{3}) are also cubed roots of 8 by cubing each and verifying the result is 8 with no imaginary part left over. 2. Using polar coordinates for the integration determine the x coordinate of the centroid for the area shown. Repeat using Cartesians coordinate with the inner integral in the y direction. You can use a known formula for the area. $x^2 + y^2 = r_o^2$ 3. Consider a circular area of radius $r_o$ centered at the origin where the 90 degree sector in the 4th quadrant is missing (3/4 of a full circle). Locate the x and y centroidal coordinates using polar coordinates for the integration. Then verify your results are on a line of symmetry. 4. Using polar coordinates determine the y coordinate for the centroid of the area. $R$ $R^2$ 5. Locate the centroid for the area shown. $y^2 = 2x$ 2 m y = -x -2 m B 2 m
