Castaneda v. Partida is an important court case in which statistical methods were used as part of a legal argument. When reviewing this case, the Supreme Court used the phrase "two or three standard deviations" as a criterion for statistical significance. This Supreme Court review has served as the basis for many subsequent applications of statistical methods in legal settings. (The two or three standard deviations referred to by the Court are values of the z statistic and correspond to P-values of approximately 0.05 and 0.0026.) In Castaneda the plaintiffs alleged that the method for selecting juries in a county in Texas was biased against Mexican Americans. For the period of time at issue, there were 180,950 persons eligible for jury duty, of whom 143,150 were Mexican Americans. Of the 881 people selected for jury duty, 346 were Mexican Americans.
(a) What proportion of eligible voters were Mexican Americans? Let this value be po. (Round your answer to four decimal places.)
(b) Let p be the probability that a randomly selected juror is a Mexican American. The null hypothesis to be tested is Ho: p = po. Find the value of p̂ for this problem, compute the z statistic, and find the P-value. What do you conclude? (A finding of statistical significance in this circumstance does not constitute a proof of discrimination. It can be used, however, to establish a prima facie case. The burden of proof then shifts to the defense.) (Use α = 0.01. Round your test statistic to two decimal places and your P-value to four decimal places.)

(c) We can reformulate this exercise as a two-sample problem. Here we wish to compare the proportion of Mexican Americans among those selected as jurors with the proportion of Mexican Americans among those not selected as jurors. Let p1 be the probability that a randomly selected juror is a Mexican American, and let p2 be the probability that a randomly selected nonjuror is a Mexican American. Find the z statistic and its P-value. (Use α = 0.01. Round your test statistic to two decimal places and your P-value to four decimal places.)

The particle moves in the presence of the magnetic field B produced by the long horizontal wire with current I=100 A flowing to the right.
A.)Find the magnitude of the magnetic field B at the location of the particle, 10 cm above the wire. Give your answer in mT (10-3 T) units.
B.)Find the direction of the magnetic field at the location of the particle.

C.)Find the magnitude of the magnetic force acting on the moving particle. (in newtons)
D.) Find the magnitude of the horizontal component of the magnetic force. (in newtons)
E.)We assume that the x axis is horizontal in the paper plane pointing to the right, y axis is in paper plane pointing up, and z axiis is horizontal pointing out of paper plane. Thus x-z is the horizontal plane.
In this coordinate system determine the direction of the horizontal component of the magnetic force (vettical component is either along y or opposite to the y axis)
Pick the proper orientatioin of the horizontal force component.

A 100 hp, 220 V, 1200 rpm DC shunt motor with an armature
resistance of 0.05 ? and a field resistance of 50 ?. The motor has
compensating windings, so armature reactance can be ignored.
Mechanical and core losses may be ignored also. The motor is
driving a drilling machine, TL ? (1/n). The motor is driving a load
with a line current of 120 A and an initial speed of 1200 rpm.

As the book-keeper for your company you are required to create quarterly financial statements (Income Statement, Statement of Owner's Equity Balance Sheet and Statement of Cash Flows) in order to report on the financial activities of the company for the quarter (three months). In your accounting classes you learned about four types of adjustments: (1) prepaid expenses, (2) unearned revenues, (3) accrued revenues, and (4) accrued expenses.
It is now March 29th, and in preparation for creating the 1st quarter's financial statements ( as of 3/31), you have called a meeting with the Dept. Managers for Accounts Receivable and Accounts Payable to confirm deadlines that have to be met for March-related transactions. As the meeting is about to start the owner walks in - she sits quietly as you explain the deadlines, but as soon as you have finished she says "Well, for this quarter, if we have not paid March invoices by March 31, there is no need to record them in March. We can record/expense those invoices when we pay them in April or May."
Required:
Do you agree with the owner, or, do you feel that an adjusting entry is necessary in the situation described? If so - which type of adjusting entry is needed?
Why is the adjustment necessary? (Refer to concepts in the chapter) In your post:
a) discuss the impact (understated or overstated) on the accounts affected if the adjustment is not made, and
b) explain how the adjustment affects the appropriate financial statements
3, Assume one of the unpaid invoices is for $2,000 in Advertising. Show the type of adjusting entry you would create.

To illustrate how to conduct rate-of-change calculations, we
will use the following example. Note that this is just an example;
the data in the table below do not match the data collected in this
experiment.

| Reduced: | 0 | 5 | 16 | 19 | 5 | 16 | |||||||
| Absent: | 0 | 7 | 1 | 0 | 12 | 4 | |||||||
Using these numbers, you need to calculate the rate of change in
the relative frequency of stickleback with a complete pelvis
per 1,000 years.
Step 1. Calculate the relative frequency of stickleback with a
complete pelvis in each layer using this formula:
|
Relative frequency = |
stickleback with a complete pelvis |
In this example, layer 1 had a total of 20 fish and 15 had a
complete pelvis; the relative frequency of fish with a complete
pelvis is 15/20 = 0.75. In other words, 75% of fish in that layer
had a complete pelvis.
For layer 2 the relative frequency of fish with a complete pelvis
is 0.5.
Step 2. Calculate the rate of change in relative frequencies
between layer 1 and layer 2—a span of 3,000 years.
To do that, you subtract the number of the older layer (layer 1)
from that of the more recent neighboring layer (layer 2).
Thus, the change in relative frequency of stickleback with a
complete pelvis between layer 1 and layer 2 = 0.5-0.75 = -0.25.
(Note that it is a negative number because the relative
frequency of fish with a complete pelvis decreased.)
Step 3. Calculate the rate of change for 1,000-year increments. To
do this, you must divide each rate of change by 3 because there are
3 1,000-year increments between layers 1 and 2, and between layers
2 and 3, and so on.
So, the rate of change in relative frequency of stickleback with a
complete pelvis between layer 1 and layer 2 per 1,000 years =
-0.25/3 = -0.083. In other words, for every thousand years between
layer 1 and layer 2 there is an average 8.3% decrease in the
relative frequency of fish with the complete pelvis.
