An article states that at least 1.8% of all soil on farms is contaminated. A researcher wishes to challenge this claim and gain evidence that the true figure is lower than this. Therefore he obtains data from 297 probes, of which five detected the soil as contaminated.

a) State the null and alternative hypotheses.

b) Show the areas of rejection and non-rejection in an appropriate diagram.

c) Test the null hypothesis to the 95% confidence level and state your conclusions. Show all your working.

d) If your conclusion were to turn out to be incorrect, state the type of error made and why.

In section 7.2 of the text, it states: “The pattern of costs varies among industries and even among firms in the same industry. Some businesses have high fixed costs, but low marginal costs.” Aside from the examples cited in the book, identify one industry with high fixed costs in the short run. Then, identify an industry with high marginal costs in the short run. Be sure to analyze specific examples of costs to justify your choices.

In this unit, the text states: “…a strategy captures and communicates how vision and mission will be achieved and which goals and objectives show that the organization is on the right path to achieving them.”

What negative consequences can emerge when vision, mission, or values contradict strategy?
Name a time where you believe strategy was not aligned with vision, mission, or values.
How can leaders ensure that strategy matches the vision, mission, and values?

Answer ASAP please!!!

  1. You are the researcher and you develop a hypothesis. It states that by providing relaxation therapy to a group of 10 smokers who average 20 cigarettes a day, you hypothesize that they will reduce the number of cigarettes they smoke after eight weeks of therapy. You will take measurements on the group you have provided relaxation therapy to after eight weeks and the mean is 16 cigarettes. You compare the mean to two other groups who did not receive the relaxation therapy. One group, n=10 received no treatment and averaged 19.7 cigarettes at the end of eight weeks, and the other group, n=10 who was given literature on the negative effects of smoking averaged 18.1 cigarettes after eight weeks. You calculate the means of all groups using the appropriate hypothesis statistic. You hypothesize that there will be a difference in the means after eight weeks. You measure smoking levels after you terminate the therapy to see if there are effects from the independent variable. The obtained test statistic is 12.396 and a p value of 0.000152. You used the alpha level of 0.05.

A report states that the mean yearly salary offer for students graduating with a degree in accounting is $48,757. Suppose that a random sample of 50 accounting graduates at a large university who received job offers resulted in a mean offer of $49,880 and a standard deviation of $3500. Do the sample data provide strong support for the claim that the mean salary offer for accounting graduates of this university is higher than the national average of $48,757? Test the relevant hypotheses using α = 0.05. (Use a statistical computer package to calculate the P-value. Round your test statistic to two decimal places and your P-value to three decimal places.)

Assume that there are three possible states of the economy: poor, moderate and booming. A firm expects to have $468,000 in sales in a poor economy, $694,000 in a moderate economy, and $915,000 in a booming economy. Suppose the profit margin, for this firm, in a poor economy is 5.6 percent, 11.5 in a moderate economy and 16.5 percent in booming economy. If the chance of a booming economy is 25% and the chance of a poor economy is 15%, what is the expected amount of profits for the firm?
A. more than $77,500 but less than $83,400
B. more than $83,400 but less than $89,300
C. more than $89,300 but less than $95,200
D. more than $95,200 but less than $101,100
E. more than $101,100
