Two-way ANOVA:
An industrial psychologist was interested in the impact of Introductory Message (general greeting, inquiry, or statement) and Type of Phone (land line or cell) on the length of a phone call. The data appear below.
Use SPSS to analyze the data and answer the following questions. Be sure to include your SPSS output (you will need to copy/paste the ANOVA table into a Word document first).

The Josephus problem is named after the historian Flavius Josephus, who lived between
the years 37 and 100 CE. Josephus was a reluctant leader of the Jewish revolt against
the Roman Empire. When it appeared that Josephus and his band were to be captured,
they resolved to kill themselves. Josephus persuaded the group by saying, “Let us commit
our mutual deaths to determination by lot. He to whom the first lot falls, let him be
killed by him that hath the second lot, and thus fortune shall make its progress through
us all; nor shall any of us perish by his own right hand, for it would be unfair if, when
the rest are gone, somebody should repent and save himself” (Flavius Josephus, The
Wars of the Jews, Book III, Chapter 8, Verse 7, tr. William Whiston, 1737). Yet that is
exactly what happened; Josephus was left for last, and he and the person he was to kill
surrendered to the Romans. Although Josephus does not describe how the lots were
assigned, the following approach is generally believed to be the way it was done. People
form a circle and count around the circle some predetermined number. When this number
is reached, that person receives a lot and leaves the circle. The count starts over with
the next person. Using the circular linked list developed in Exercise 6, simulate this problem.
Your program should take two parameters: n, the number of people that start, and
m, the number of counts. For example, try n = 20 and m = 12. Where does Josephus need
to be in the original list so that he is the last one chosen?

The suicide rate in a certain state is 1 suicide per 100,000 inhabitants
per month. In a city with population 400,000, and the probabilities of the
following events. Your answers should be numerical; if they are approximate,
explain your approximation.
(a) There will be 8 or more suicides in one month.
(b) What is the probability that in a given year there will be at least two months with 8 or more suicides?

I am trying to figure out the probability, expected value, variance, and standard deviation for a series of dice rolls. For example, if I roll a six-sided die in an attempt to roll a 1, and it takes me 7 rolls before a 1 appears, what are those answers? I have figured out the probability equation:
P(P-1)^x where x is the number of rolls - 1 so for 7 rolls the probability would be: 1/6(1-1/6)^6 = 0.05581632...
Further where I am lost is taking the above and using it to find the Expected Value, Variance, and Standard Deviation?
As I see the equations but plugging in numbers has me lost as p is the probability of failure and x = 0,1,2,3 for geometric distribution it would be
E(X)= (1-p)/p .... this is where I am lost as failure is 5/6 not 1/6 correct? Please show example of this so I can better understand, also on Variance, and Standard Deviation?

Juanita is deciding whether to buy a skirt that she wants, as well as where to buy it. Three stores carry the same skirt, but it is more convenient for Juanita to get to some stores than others. For example, she can go to her local store, located 15 minutes away from where she works, and pay a marked-up price of $130 for the skirt:
| Travel Time Each Way | Price of a Skirt | |
|---|---|---|
| Store | (Minutes) | (Dollars per skirt) |
| Local Department Store | 15 | 130 |
| Across Town | 30 | 86 |
| Neighboring City | 60 | 60 |
Complete the following table by computing the opportunity cost of Juanita's time and the total cost of shopping at each location.
| Store | Opportunity Cost of Time (Dollars) | Price of a Skirt (Dollars per skirt) | Total Cost (Dollars) |
|---|---|---|---|
| Local Department Store | 130 | ||
| Across Town | 86 | ||
| Neighboring City | 60 |
Assume that Juanita takes opportunity costs and the price of the skirt into consideration when she shops. Juanita will minimize the cost of the skirt if she buys it from the store in the neighboring city.

1.Marginal profit is equal to marginal revenue plus marginal cost.
True or false
Spacely Sprockets' short-run cost curve is C(q,K)=25q2K+15KC(q,K)=25q2K+15K, where q is the number of Sprockets produced and K is the number of robot hours Spacely hires. Currently, Spacely 2.hires 10 robot hours per period. The short-run marginal cost curve is MC(q,K)=50qKMC(q,K)=50qK. If Spacely receives $250 for every sprocket he produces, his profit maximizing output level is 50.

3.Consider a competitive market in which the market demand for the product is expressed as P = 75 - 1.5Q, and the supply of the product is expressed as P = 25 + 0.5Q. Price, P, is in dollars per unit sold, and Q represents the rate of production and sales in hundreds of units per day. The typical firm in this market has a marginal cost of MC=2.5+10qMC=2.5+10q.
In this case, the typical firm will maximize its profit at the point where MC = P =
