The manufacturer of the drug claims that more than 91% of patients taking the drug are healed within 8 weeks. In clinical trials, 218 of 238 patients suffering from acid reflux disease were healed after 8 weeks. Test the manufacturer's claim at the $\alpha = 0.05$ level of significance. Because $n p_0 (1 - p_0) = 19.5 > 10$, the sample size is requirements for testing the hypothesis (Round to one decimal place as needed.) What are the null and alternative hypotheses? $H_0: p$ $0.91$ versus $H_1: p$ $0.91$ (Type integers or decimals. Do not round.) Find the test statistic, $z_0$. $z_0 = \Box$ (Round to two decimal places as needed.) less than 5% of and the sample can be reasonably assumed to be random, the are satisfied.

Consider the two-period endowment model. Assume the consumers' preference over current and future consumption is given by U(c, c^')=c^1/2 c^'1/2. The consumer is endowed with y units of goods in the current period and y^' units of goods in the future period. Further assume there is no government (no taxes or government expenditures). The interest rate is r. (a) Write down the consumer's problem. What variables are taken as given? What variables are the consumer's choices? (b) Write the Lagrangian and derive the first-order conditions of the consumer's problem. Interpret the first-order conditions. (c) Solve for the optimal decisions: c, c^' and s as functions of y, y^', r. Show your work. (d) Looking at the case of a net borrower, what do we have to assume about the substitution and income effects to generate the result that a decrease in r brings about an increase in current-period consumption? Explain your answer.

For an equation like $x^2 - 4x + 4 = 0$, a root exists at $x = 2$. The bisection method cannot be adopted to solve this equation in spite of the root existing at $x = 2$ because the function Has a slope equal to zero at $x = 2$ Has two different roots Is a polynomial Is always non-negative Has repeated roots at $x = 2$
