1) A protein shake company Bulk Builders has been taking data on how their shake builds muscles. The data from their population is average Joe gains a µ=10lbs of muscle, with a standard deviation of 4 lbs. The company would like to make better claims and wants to know what the probability of getting a gain of SEM=20lbs. You will need to find the z score but, first draw the normal curve and shade in the area that they are interested in finding.

2) An Industrial Organizational (IO) psychologist got some data from a test they did on productivity. They collected productivity scores (from 1-100 points) from n=8 participants. The scores were: 78, 85,64, 90 and 88.
a. Find the mean variance, and standard deviation of this group.
b. Suppose the µ=76, what is the z score?
c. What is the probability of getting this mean-draw the curve!
d. What is the SEM for this particular group?

This is straight from my teachers HW, there is no other data. If anything answer for either of these and I'll give you an upvote.

Expert Solution

This problem uses the concept of Normal Distribution, first we calculate the z score , then we find the probability using the z scores

Consider a hypothetical Intracellular protein Z. This protein has been shown to be 1) overexpressed in cancer samples compared to normal tissues (western blot), (2) it is not secreted by cells, and (3) it is expressed by endothelial cells in a tumor-associated vasculature. as shown by immunohistochemistry Propose 5 experiments that you could use to test that your protein Z plays a role in angiogenesis. Experiments should be done within 6 months.

A protein is being separated on a chromatography column. The protein has been found to obey the Langmuir isotherm, with Stot= 300 µg/mL and Keq= 10 mL/mg. The concentration of the protein in the feed (3 liters) to the column is 2 mg/mL. The column flow rate is 2.0 liters/min. The column is 50 cm in diameter and 100 cm long. The void fraction of the chromatography bed is 0.35. Determine (a) the time for the protein shock front to...

Historically, the exercise of eminent domain has been limited to the taking of private lands for public works projects---roads, schools, water treatment projects, etc. Within the past couple of years in the Northeast, a city took (via its power of eminent domain) private land to be used for private commercial purposes as a means to increase the municipality's tax base (i.e., taking family homes for the construction of a Wal-Mart, although this was not exactly the case in this instance)....
