Two lasers, one red (with wavelength 633.0 nm) and the other green (with wavelength 532.0 nm), are mounted behind a 0.150-mm slit. On the other side of the slit is a white screen. When the red laser is turned on, it creates a diffraction pattern on the screen. The distance y3,red from the center of the pattern to the location of the third diffraction minimum of the red laser is 4.05 cm. How far L is the screen from the slit?

The manufacturer of a new chewing gum claims that at least 80% of dentists surveyed prefer their type of gum and recommend it for their patients who chew gum. An independent consumer research firm decides to test their claim. The findings in a sample of 200 dentists indicate that 74.1% of the respondents do actually prefer their gum. What are the null and alternative hypotheses for the test? Question 11Select one: a. H0: P >= 0.80 and H1: P < 0.80 b. H0: P <= 0.80 and H1: P > 0.80 c. H0: P > 0.80 and H1: P <= 0.80 d. H0: P = 0.80 and H1: P != 0.80 The value of the test statistic is: Question 13Select one: a. -1.444 b. 2.086 c. 1.444 d. -2.086 Which of the following statements is most accurate? Question 14Select one: a. Reject the null hypothesis at α = 0.01 b. Fail to reject the null hypothesis at α <= 0.10 c. Reject the null hypothesis at α = 0.05 d. Reject the null hypothesis at α = 0.10, but not 0.05 If conducting a two-sided test of population means, unknown variance, at a level of significance 0.05 based on a sample of size 20, the critical t-value is: Question 15Select one: a. 2.086 b. 1.725 c. 2.093 d. 1.729

3. A consumer with income $I$ facing prices $p_x$ and $p_y$ has the following indirect utility function for goods X and Y: $V(p_x, p_y, I) = \frac{1}{2}p_y^{-1/2}(p_x^{1/2} + p_x^{-1/2}I)$ a. Derive the consumer's Hicksian demand function for good X. b. Check that the properties of Hicksian demand functions are satisfied. c. Suppose $I = 49$, $p_y = 1$, and $p_x = 1$. Compute the consumer's compensating variation $(CV)$ and their equivalent variation $(EV)$ for an increase in $p_y$ from 1 to 4. d. Use words and a graph to interpret your CV and EV measures.
