Consider the closed-loop amplifier configuration shown in Figure 2a, and assume that the op-amp is ideal.                                          Figure 2a   a) Derive an expression for the voltage gain (vo/vi) of the amplifier configuration given in Figure 2a.  Express this voltage gain in terms of R1, R2, R3, etc.

c)  Consider the MOSFET cross-section of Figure 1c below. What type of MOSFET is this and in which region is this MOSFET operating (e.g. saturation, triode, etc) ? HOW do you know this? NOTE: current iD is flowing in this diagram.                                                Figure 1c

Total lung capacity can be exactly calculated.

You are right in front of the stage at a concert with your favorite band and you are trying to tell your best friend how much fun you are having. The reason you shout at your friend is likely explained by:

In a ggplot visualization, what is the primary purpose of using the aes() function?

A high-end handbag designer is testing their latest handbag designs to improve sales. Version A features a slightly larger handbag, while Version B highlights a smaller-style handbags. The designer selects two groups V1 and V2 to run an A/B test. Group V1 rates the larger bag and group V2 rates the smaller style. You can consider the rating to be on a scale of 1-10. Assuming a significance level of 0.01. Define a clear null hypothesis and alternative hypothesis for this A/B test. Identify the independent variable and the dependent variable. Would the extraneous variables be addressed  if V1 and V2 were selected from outside of the U.S.? Justify your answer, Can you use a two-sample t-test assuming equal variances? Justify your answer. Under which conditions would you reject or fail to reject the null hypothesis?
