Europe who use the Internet? A.0.321 < p < 0.379 B.0.316 < p < 0.384 C.0.309 < p < 0.391 D.0.305 < p < 0.395
Answer Key: B Part 6 of 16 - 1.0/ 1.0 Points Question 13 of 23 1.0/ 1.0 Points The theorem that states that the sampling distribution of the sample mean is approximately normal when the sample size n is reasonably large is known as the: A.central limit theorem B.point estimate theorem C.central tendency theorem D.simple random sample theorem Answer Key: A Part 7 of 16 - 1.0/ 1.0 Points Question 14 of 23 1.0/ 1.0 Points A multiple choice quiz consists of 6 questions, each with 4 possible answers. If a student guesses at the answer to each question, then the mean number of correct answers is A.6.00 B.1.50 C.4.00 D.10.00
Answer Key: B Part 8 of 16 - 0.0/ 1.0 Points Question 15 of 23 0.0/ 1.0 Points What type of probability uses sample spaces to determine the numerical probability that an event will occur? A.empirical probability B.classical probability C.subjective probability D.conditional probability Answer Key: B Feedback: See the discussion of "classical probability" on page 194. Part 9 of 16 - 1.0/ 3.0 Points Question 16 of 23 1.0/ 3.0 Points Accepted characters : numbers, decimal point markers (period or comma), sign indicators (-), spaces (e.g., as thousands separator, 5 000), "E" or "e" (used in scientific notation). NOTE: For scientific notation, a period MUST be used as the decimal point marker. Complex numbers should be in the form (a + bi) where "a" and "b" need to have explicitly stated values. For example: {1+1i} is valid whereas {1+i} is not. {0+9i} is valid whereas {9i} is not.
Staples, a chain of large office supply stores, sells a line of desktop and laptop computers. Company executives want to know whether the demands for these two types of computers are dependent on one another. Each day's demand for each type of computers is categorized as Low, Medium-Low, Medium- High, or High. The data shown in the table below is based on 200 days of operation. Based on these data, can Staples conclude that demands for these two types of computers are independent? Test at the 5% level of significance. desktops low med-low med-high high low 3 14 14 4 35 laptops med-low 6 18 17 22 63 med-high 13 16 11 16 56 high 8 14 15 9 46 30 62 57 51 200 What is the test value for this hypothesis test? Answer: 4.332 Round your answer to two decimal places. What is the critical value for this hypothesis test? Answer: 5.683 Round your answer to two decimal places. What is the conclusion for this hypothesis test? Choose one. 1. At the .05 level of significance, Staples can conclude that demands for these two types of computers are independent. 2. At the .05 level of significance, Staples can conclude that demands for these two types of computers are dependent. Answer: 1 Enter only a 1 or 2 for your answer. Answer Key: 15.31, 16.92, 1 Part 10 of 16 - 1.0/ 1.0 Points
Question 17 of 23 1.0/ 1.0 Points Accepted characters : numbers, decimal point markers (period or comma), sign indicators (-), spaces (e.g., as thousands separator, 5 000), "E" or "e" (used in scientific notation). NOTE: For scientific notation, a period MUST be used as the decimal point marker.
