Bicycling, the world's leading cycling magazine, reviews hundreds of bicycles throughout the year. Their "Road-Race" category contains reviews of bikes used by riders primarily interested in racing. One of the most important factors in selecting a bike for racing is the weight of the bike. The following data show the weight (pounds) and price ($) for 10 racing bikes reviewed by the magazine.
(a) Use the data to develop an estimated regression equation that could be used to estimate the price for a bike given the weight. (Round your numerical values to the nearest integer).
(b) Computer r2. (Round your answer to three decimal places.)
(c) Predict the price (in dollars) for a bike that weighs 16 pounds. (Round your answer to the nearest dollar.)

You are evaluating two magazines in which to advertise and reach the 18-34 year-old female audience. These two magazines are Field & Stream (a hunting and fishing enthusiasts’ magazine whose readership is 75% male) and Cosmopolitan (a fashion/lifestyle magazine targeting young women in their 20s and 30s). One page in Field & Stream costs $50,000 with a circulation of 1,500,000 readers. One page in Cosmopolitan costs $150,000 with a circulation of 2,500,000 readers, 90% female under the age of 40. What is the CPM of both magazines ( Field & Stream and Cosmopolitan) and briefly discuss the efficiency and effectiveness of each media vehicle, given the target audience of 18-34 females.

In the summer of 2014, a popular magazine selected a random sample of its subscribers and invited them to vote on its website for their favorite sips of the summer. The results were reported as follows: drink A, 35%; drink B, 30%; drink C, 20%; and drink D, 15%. To test the claim that preference has changed after 5 years, the magazine conducted a similar survey and reported the outcome based on 1,600 randomly selected respondents. The votes for the favorite sips were, 600 for drink A; 420 for drink B; 330 for drink C; and 250 for drink D. Find the value of the test statistic for testing the appropriate hypotheses? Round your answers to the nearest ten-thousandth (4 decimals).

A national grocer’s magazine reports the typical shopper spends 10 minutes in line waiting to check out. A sample of 20 shoppers at the local Farmer Jack’s showed a mean of 9.6 minutes with a standard deviation of 3.7 minutes. Is the waiting time at the local Farmer Jack’s less than that reported in the national magazine? Use the 0.025 significance level. What is the decision rule? (Negative amount should be indicated by a minus sign. Round your answer to 3 decimal places.) Compute the value of the test statistic. (Negative amount should be indicated by a minus sign. Round your answer to 2 decimal places.) What is your decision regarding H0? Reject H0 Do not reject H0

The owner of Christie’ Bookstore is looking into the sales of its Health & Fitness magazine section. She finds that her equilibrium is at 1000 magazines per month sold at an average price of $4.25 per magazine. When the average price of these Health & Fitness magazines rose to $4.95 each, the quantity demanded fell to 900 magazines per month, while the quantity supplied to her increased to 1250 a month.

Kenya and South Africa are trading partners, and there are capital flows between the two countries. The currency in Kenya is the Kenyan shilling (Ksh.) and the currency in South Africa is the South African Rand (R). Assume that the equilibrium exchange rate is 0.14R per Kenya shilling. Now suppose that the opportunity cost of consumption falls in South Africa.
Referring to the Kenyan foreign exchange market, explain how the equilibrium exchange rate might change. You are not required to draw the graphs - all you need to do is explain in detail how the exchange rate could change. Remember to include both demand and supply shifts in your explanation, and indicate a possible new exchange rate in this market.

There are wetlands that exist in South Dakota. I would like you to tell me the type of the wetlands in the state (I am thinking specifically the wetlands in the Lacreek refuge and the wetlands in eastern South Dakota-they are different types). Classify them, provide the value and function of them. Be sure to tell me about the plants, animals, macroinvertebrates, water quality-chemistry, soil types, etc. Why are wetlands important in these areas of South Dakota? What is the keystone species of the wetlands? How is this species important to the wetlands in South Dakota. Is Pollution affecting the wetlands in South Dakota? What is causing this pollution? How could you change that? Is Climate change affecting the wetlands? How/Why? You should have 2 full pages (double spaced of typing, 12 pt font, 1 inch margins, calibri or new time roman font). You can add photos and charts but make sure that you have 2 pages of writing (if I was to extract the photos and charts you should still have 2 pages of writing)

The price to earnings ratio (P/E) is an important tool in financial work. A random sample of 14 large U.S. banks (J. P. Morgan, Bank of America, and others) gave the following P/E ratios.†
| 24 | 16 | 22 | 14 | 12 | 13 | 17 | 22 | 15 | 19 | 23 | 13 | 11 | 18 |
The sample mean is
x ≈ 17.1.
Generally speaking, a low P/E ratio indicates a "value" or bargain stock. Suppose a recent copy of a magazine indicated that the P/E ratio of a certain stock index is μ = 20. Let x be a random variable representing the P/E ratio of all large U.S. bank stocks. We assume that x has a normal distribution and σ = 5.1. Do these data indicate that the P/E ratio of all U.S. bank stocks is less than 20? Use α = 0.01. z value was -2.13 (rounded answer).
Find (or estimate) the P-value. (Round your answer to four decimal places.)
will you reject or fail to reject the null hypothesis? Are the data statistically significant at level α?
At the α = 0.01 level, we reject the null hypothesis and conclude the data are statistically significant.
At the α = 0.01 level, we reject the null hypothesis and conclude the data are not statistically significant.
At the α = 0.01 level, we fail to reject the null hypothesis and conclude the data are statistically significant.
At the α = 0.01 level, we fail to reject the null hypothesis and conclude the data are not statistically significant

At the time of this writing, voters are particularly disgruntled. A good many seem to be disgusted with government. For this question, we intentionally avoid distinguishing between Democrats and Republicans, and we intentionally do not name any particular President.

Consultex, Inc., was founded in 2015 as a small financial consulting business. The company had done reasonably well in 2015–2017 but started noticing its cash dwindle early in 2018. In January 2018, Consultex had paid $15,000 to purchase land and repaid $3,000 principal on an existing promissory note. In March, the company paid $1,800 cash for dividends and $1,000 to repurchase and eliminate Consultex stock that had previously been issued for $1,000. To improve its cash position, Consultex borrowed $4,800 by signing a new promissory note in May and also issued stock to a new private investor for $11,800 cash. Year-end comparative balance sheets and income statements are presented below.
