Suppose we are interested in the proportion of people who prefer Lays chips to a store brand chip.  In particular, we want to test whether this proportion is greater than 0.5.  In a taste test based on a random sample of 50 people, 29 of them preferred Lays.  Is this compelling evidence that the population proportion is actually greater than 0.5? Let 𝑝 be the population proportion of people who prefer Lays.  What are the appropriate hypotheses for the test?Single choice

A

𝐻 0 : 𝑝 = 0.5 versus  𝐻 𝐴 : 𝑝 > 0.5

B

𝐻 0 : 𝑝 = 0.5 versus 𝐻 𝐴 : 𝑝 < 0.5

C

𝐻 0 : 𝑝 = 0.5 versus 𝐻 𝐴 : 𝑝 ≠ 0.5

A bark beetle infestation will kill off a pine forest in months. To deal with this problem rangers conduct controlled burns if the bark beetle infests more than 10% of all pine trees in the forest. 1500 randomly selected Tahoe pine trees in a very large national park were tested for traces of the Bark Beetle infestation.  It was found that 153 of the trees showed such traces.  They wish to test that more than 10% of the Tahoe trees have been infested.  (Use a 5% level of significance).  What are the appropriate hypotheses for this test?

A news report claims that 32% of households own at least one cat. Believing the true percentage of households that own at least one cat exceeds 32%, a researcher surveys a random sample of 200 households and finds that in 74 of these households, there is at least one cat.  From this information, which one of the following statements is false?

A movie critic conducts a hypothesis test because he has a theory that the proportion of adults who enjoy scary movies falls well below 0.45.   After surveying a random sample of adults and conducting a hypothesis test, the movie critic reports a P-value of 0.01.  Assuming the movie critic was using a sample size that was large enough to meet hypothesis testing conditions and that no calculation mistakes were made, what can we conclude based on this information?

Pedersen Industries wants to initiate a new project. To facilitate the project, an increase in cash of $20,000 will be required and the firm needs to build up $15,000 in inventory. The firm is expecting revenues of $500,000 per year and cost of goods sold (COGS) of $400,000. Pedersen Industries is expecting that Accounts Receivables (AR) will account for 5% of annual sales and Accounts Payables (AP) will account for 10% of COGS. All these changes will occur in year t=1. ​ What is the incremental cash flow effect from the change in Net Working Capital (NWC) in year 1?
