Consider this quote: "In a recent survey, 76 out of 100 consumers reported that they preferred plastic bags instead of paper bags for their groceries. If there is no difference in the proportions who prefer each type in the population, the chance of such extreme results in a sample of this size is about .03. Because .03 is less than .05, we can conclude that there is a statistically significant difference in preference." Give a numerical value for each of the following. (a) The p-value. (b) The level of significance, \alpha . (c) The sample proportion. (d) The sample size. (e) The null value.

Imagine that you sequenced a new bacterial genome using high throughput sequencing. In the sequencing reads you observed the following nucleotide frequencies: A: 20%, T: 30%, G: 22%, C: 28% How would you interpret this result? The bacterial strain has been infected with a single stranded DNA bacteriophage Based on the data, you cannot distinguish whether the

QUESTION 11 As the manager of a video store, you know that the number of sales of the hottest new movie releases is normally distributed with an average of 85 copies within the first week (with a standard deviation of 13). You want to be 90% sure that you have enough copies to sell in the first week. How many copies should you order? (please round your answer to 2 decimal places) QUESTION 12 The lifetime of a DVD player is normally distributed with a mean of 8 years and a standard deviation of 38 months. What is the probability that the DVD player that you just bought will last longer than 12 years (144 months) (please round your answer to 4 decimal places)

Consider five threads: T0, T1, T2, T3, T4; and three resource types: A, B, C. Here, A has 12 instances, B has 8 instances, and C has 9 instances. The current state of the system is presented on Table 1, where 'Allocation' represents the number of instances for each resource type currently allocated to each thread, and 'Max' represents the maximum demand of each thread. Answer the following questions based on Banker's Algorithm: a. Is the system in a safe state now? b. If the system is in a safe state, what is the corresponding safe sequence? It would suffice to present one safe sequence in your answer. Note: You must show the steps how you found the safe sequence.

Let I be the half-open interval [0,1] in R and let C(I,d) be the metric space of all bounded continuous functions f : I -> IR equipped with the uniform (i.e. supremum) metric d. For each k in N, define f_k in C(I,d) by f_k(x) = 1 / sqrt(x) where 0 < x <= 1, and let A be the zero function in C(I,d) where x = 0. a) Show that f_k converges pointwise on I as k approaches infinity, but that {f_k} does not converge on I to A under d. b) Briefly explain why the metric space C(I,d) is complete and why your answer to part a is consistent with this fact. Justify your answer. c) Show that g defined by g(x) = 1 + f_k(x) - 1 / n^(3/2) * x is a contraction mapping on I. Explain why g has no fixed point in I and why this does not contradict the contraction mapping theorem. Hint: You can use that n > 1 for all n in N.
