An article posted on your college's website claims that 12% of the students at the school use marijuana. You randomly sample 140 students, and 12 students reply that they do indeed use marijuana. You want to conduct a hypothesis test at a 5% level of significance.
What should your conclusion be?
|
You can reject the claim made in the article, since the p-value is less than 0.05. The proportion of students that use marijuana is likely less than 12%. |
||
|
You can not reject the claim made in the article, since the p-value is greater 0.05. The claim that 12% of students use marijuana should be considered accurate. |
||
|
You can not reject the claim made in the article, since the p-value is greater 0.05. There is not sufficient evidence in the sample to dispute the claim that 12% of students use marijuana. |

Patriot Co. manufactures and sells three products: red, white, and blue. Their unit selling prices are red, $20; white, $35; and blue, $65. The per unit variable costs to manufacture and sell these products are red, $12; white, $22; and blue, $50. Their sales mix is reflected in a ratio of 5:4:2 (red:white:blue). Annual fixed costs shared by all three products are $250,000. One type of raw material has been used to manufacture all three products. The company has developed a new material of equal quality for less cost. The new material would reduce variable costs per unit as follows: red, by $6; white, by $12; and blue, by $10. However, the new material requires new equipment, which will increase annual fixed costs by $50,000. Required: 1. Assume if the company continues to use the old material, determine its break-even point in both sales units and sales dollars of each individual product. (Round composite units up to next whole number.)

1. A random number generator claims to randomly choose real numbers between 0 and 3000. (a) If this is true, what kind of distribution would the randomly chosen numbers have? (b) What would be the mean of this distribution? (c) What would be the standard deviation of this distribution? (d) Say we take a sample of 65 generated numbers and obtain a sample mean of 1552. What do we know about the sampling distribution of the sample mean and how do we know this? (e) Give a 99% confidence interval about the population mean. (f) In a sentence or two, state what the 99% confidence interval from(e) tells us. (g) Suppose that we do not know the population standard deviation and, instead,the sample standard deviation is s = 822. What is the confidence interval about the population mean using the sample standard deviation? Compare this to your answer in part (e).
