Concept Check: Name the test A psychologist wants to test whether a group of 20 participants' average stress level differs from the general population average of 50. The population standard deviation is unknown. A group of 30 students takes a math test, follows a study program, and then takes a similar test after the program. The researcher wants to see if the students improved. A researcher compares test scores between two groups: 25 students who studied using a new method and 25 students who used a traditional method. A researcher wants to compare the average IQ of a sample of 100 high school students to the known population IQ average of 100, and the population standard deviation is known ($\sigma$ = 15)

6. Several pigments were isolated from blueberry leaves using the same procedure described in this experiment. Each purified pigment was characterized by absorbance spectrophotometry. Based on the information below, identify the plant pigment present in each band. The possibilities are chlorophyll a, chlorophyll b and $\beta$-carotene. a) One band has absorption peaks at 410 nm, 428 nm, and 660 nm. What pigment is present in this band? Explain. b) Another band has absorption peaks at 450 nm and 480nm. What pigment is present in this band? Explain. c) A third band has absorption peaks at 430 nm, 455 nm, and 650 nm. What pigment is present in this band? Explain.

O interrupt instruction execution two clocks cycles after Interrupt flag is set up to 1. O interrupt instruction execution immediately after Interrupt flag is set up to 1. O Never interrupt instruction execution after Interrupt flag is set up to 1. O Switch program execution to the instruction in the stack before the current instruction is completed. O Switch program execution to the instruction in the stack after the current instruction is completed.

(3) A bar is subjected to the axial loading. The normal stress is: $S_x = \frac{F}{\pi d^2 / 4}$. The failure mode of the bar will be the static failure. The yield strength $S_y$, axial loading F and dimeter d all follow the normal distribution. The parameters of the normal distribution are listed in the following table. Yield strength $S_y$ (psi) $S_y \sim N(61000,5200)$ Axial loading F (lb) $F \sim N(60000,15000)$ (a) Build and explain two different forms of the limit state functions The diameter d (in) $d \sim N(1.5,0.021)$ (b) Use the FOSM method to determine the reliability based on the two limit state functions
