The surface tension of a fluid depends upon the viscosity μ, bulk modulus EV, gravity g, pressure p, velocity v, density Ƿ, and a characteristic length L. determine the dimensionless groupings. USE MLT and V, L, Ƿ as repeating variables. A your Pi terms among the common dimensionless groups in Fluid Mechanics?

If you draw a random sample of 1000 College Students and you find that the average GPA of the students is 3.5 with a standard deviation of 0.5, what is the distribution of the average GPA? Someone argues that the average GPA of all college students is 2.5. Does your sample support that? What is your 95% CI for the population average?

A group of 76 randomly selected students have a mean score of 29.5 with a standard deviation of 5.2 on a placement test. Construct and interpret a 95% confidence interval for the mean score, μ, of all students taking the test. Construct and interpret a 95% confidence interval for the mean score, μ, of all students taking the test.

The international programs office on campus wants to publicize the news that the enrollment of international students on campus will set a record of 1,000 students for fall semester. They will come from 90 nations, with China number one and India number two in terms of students. Write a 60-second audio news release (ANR) that includes a soundbite.

If student arrivals to the school dining commons follows the Poisson distribution with a mean of 50 students per day. For a randomly selected 36 days: (use 4 digits after decimal point)

What is the probability that they served breakfast to at least 1757 students during these 36 days? [hint: P(ΣX ≥ 1757 students) =?]

Grades on a standardized test are known to have a mean of 940 for students in the United States. The test is administered to 436 randomly selected students in​ Florida; in this​ sample, the mean is 952.22 and the standard deviation ​(s​) is 101.52.

The​ 95% confidence interval for the average test score for Florida students is ​(__ , __). ​(Round your responses to two decimal places.​)

A random sample size of 1000 school children from urban areas shows average height is 150cm with an S.D. of 45.2cm. Similar sample of students from rural school has average height of 146 cm. with an SD of 37.3cm. Are students from urban area taller than students from rural area?

The demand function for a truckload of firewood in a small town with a college is Q = 200 - 1.5p for non-students and Q = 200 - p for students, where p is the price of firewood, in $/truckload. For the town as a whole, including the students, the slope of the inverse demand curve to the right of the kink is ? A. -1 B. -2 C. -.5 D. -.4

Three jars each have volume V and height h, but they have different shapes as shown in (Figure 1) . Water is to be added to each jar and the pressure is to be measured right at the bottom of each jar.

Figure 1

Part A

Rank the jars in order of decreasing pressure if the volume of water is V.

Rank from largest to smallest. To rank items as equivalent, overlap them.

P_a, P_{c ,} P_b

or correct ranking cannot be determined.

Part B

Rank the jars in order of decreasing pressure if the volume of water is V/2.

Rank from largest to smallest. To rank items as equivalent, overlap them.

P_{b ,} P_{a ,} P_c

or correct ranking cannot be determined
