24.  The nurse is caring for a patient who has an order to place an indwelling catheter.  Which of the following assessments will the nurse perform prior to insertion? (Select All that Apply.)

8. If blood pressure drops below the normal range, what should happen to the glomerular filtration rate to compensate for this drop?

We want to generate a 90% confidence interval for μ. The sample size is 20. We know the population of x values is normally distributed, but we do not know the population standard deviation. Which distribution: z, t, or neither should be used when constructing a confidence interval?  

A politician claims that over 70% of his constituents favor a new ballpark. You wish to test this claim. Determine whether the hypothesis test for this claim is left-tailed, right-tailed, or two-tailed.

Long Question 1 (Total 20 points) Tests the Core outcomes 2 ProblemConsider a feedback system below with G = 1/(s+1).  You’ll design a controller K(s) and if needed F(s) to meet all of the following specifications If r = 1   (i.e. a step) then in the steady state y(t) is between 0.9 to 1.1 (i.e., |error|

Long Question 2 (Total 20 points) Tests the Core outcomes 2 Problem Consider a feedback system below to control a standing robotThe TF from input torque u to robot angle y (in rad) is G = 1/(s^2  – 4). Note: this TF has poles at +2 and -2. The TF of the angle sensor from the angle y (in rad) to measured angle ym (in rad) is H = 1/(s+3).  You want the robot to lean uniformly at the rate of 0.1 rad/s. Thus, r = 0.1*t . Design a controller C(s) and prefilter F(s) to meet all of the following specifications.  if r=0.1*t (i.e., a ramp) then y has no steady state error in following it.  The settling time of the system should be less than 2s. Torque u(t) should remain finite. The overshoot is not a problem, anything is fine.  Don’t cancel the unstable plant pole at +2, it would lead to bad disturbance response. There is a huge penalty for cancelling it.  Disturbance du = 0.  Procedure  Work neatly on paper showing all the steps needed to get to the final K(s).Neat + clean + organized  = extra credit! Then show your papers to camera. Just type your final C(s) (and if needed F(s) ) below, rest all will be graded based on paper work submitted after the exam. After exam, submit your work as a pdf on canvas.   Answer the following parts. Be SUPER organized and neat. What do you need and C(s) (and if needed F(s))to meet the error specification?Explain briefly and mathematically.  (3 points) What region in the 2D complex plane should the closed loop poles be so that the settling time specifications is met?Explain briefly and mathematically. ( 3 points) What do you need and C(s) (and if needed F(s)) to ensure u(t) shall be finite for ramp r(t). (4 points) By plotting the root locus explain what type of controller is needed to meet ALL the specifications.i.e., what symbolic controller poles and zeros (if any) are needed to meet all the specifications. (6 points) Perform the closed-loop calculations to find your final transfer functions C(s) and F(s) to meet ALL the specs. i.e. find the numerical values of gain/pole/zeros of C(s) and F(s) to get their transfer functions. (4 points)

According to Annie Lowrey, what hidden cost does the public bear because of low wages paid by profitable companies?

Economic forces, such as outsourcing and automation, are no longer polarizing the workforce.

U.S. Census statistics show that Women are still earning only 75 percent of what men are for the same positions.

People in poverty pay significantly more for their housing than others. Sometimes they pay 90-95 percent of their total income towards housing.
