Soft and Silky, Inc. manufactures bedding sets. The budgeted production is for 53,000 comforters in 2017. Each comforter requires 6 yards of material. The estimated January 1, 2017, beginning inventory is 31,000 yards. The desired ending balance is 30,000 yards of material. If the material costs $1.50 per yard, determine the materials budget for 2017.

Suppose that for a recent admissions class, an Ivy League college received 2,851 applications for early admission. Of this group, it admitted 1,033 students early, rejected 854 outright, and deferred 964 to the regular admission pool for further consideration. In the past, this school has admitted 18% of the deferred early admission applicants during the regular admission process. Counting the students admitted early and the students admitted during the regular admission process, the total class size was 2,375. Let E, R, and D represent the events that a student who applies for early admission is admitted early, rejected outright, or deferred to the regular admissions pool.Use the data to estimate P(E ), P(R), and P(D). If required, round your answers to four decimal places.(a)P(E) =P(R) =P(D) =(b) Are events E and D mutually exclusive? Find P(E ∩ D). If your answer is zero, enter "0".(c) For the 2,375 students who were admitted, what is the probability that a randomly selected student was accepted during early admission? If required, round your answer to four decimal places.(d) Suppose a student applies for early admission. What is the probability that the student will be admitted for early admission or be deferred and later admitted during the regular admission process? If required, round your answer to four decimal places.

Suppose you are planning an experiment to test the effects of various diets on the weight gain of young turkeys. The observed variable will be gain in three weeks (measured over a period starting one week after hatching and ending three weeks later). Previous experiments suggest that the standard deviation of under a standard diet is approximately 80 g. Using this as a guess of ????????, determine how many turkeys you should have in a treatment group, if you want the standard error of the group mean to be no more than (a) 20 g (b) 15 g

A recent college graduate is planning to take the first three actuarial examinations in the coming summer. She will take the first actuarial exam in June. If she passes that exam, then she will take the second exam in July, and if she also passes that one, then she will take the third exam in September. If she fails an exam, then she is not allowed to take any others. The probability that she passes the first exam is .9. If she passes the first exam, then the conditional probability that she passes the second one is.8, and if she passes both the first and the second exams, then the conditional probability that she passes the third exam is .7 (a) What is the probability that she passes all three exams? (b) Given that she did not pass all three exams, what is the conditional probability that she failed the second exam?

(CO 5) An advocacy group claims that the mean braking distance of a certain type of tire is 75 feet when the car is going 40 miles per hour. In a test of 45 of these tires, the braking distance has a mean of 78 and a population standard deviation of 5.9 feet. Find the standardized test statistic and the corresponding p-value. Group of answer choices

To find the 90% confidence interval for the population standard deviation, you randomly sample with replacement from the original sample thousands of times. From each new sample, you compute the sample standard deviation. Using the bootstrap method, how can you find the 90% confidence interval for the population standard deviation from these values?

Show all your work. Indicate clearly the methods you use. As part of the President's Challenge, students can attempt to earn the Presidential Physical Fitness Award or the National Physical Fitness Award by meeting qualifying standards in five events: curl-ups, shuttle run, sit and reach, one-mile run, and pull-ups. The qualifying standards are based on the 1985 School Population Fitness Survey. For the Presidential Award, the standard for each event is the 85th percentile of the results for a specific age group and gender among students who participated in the 1985 survey. For the National Award, the standard is the 50th percentile. To win either award, a student must meet the qualifying standard for all five events. Jane, who is 9 years old, did 40 curl-ups in one minute. Matt, who is 12 years old, also did 40 curl-ups in one minute. The qualifying standard for the Presidential Award is 39 curl-ups for Jane and 50 curl-ups for Matt. For the National Award, the standards are 30 and 40, respectively. Compare Jane's and Matt's performances using percentiles. Explain in language simple enough for someone who knows little statistics to understand.

To estimate the mean score μ of those who took the Medical College Admission Test on your campus, you will obtain the scores of an SRS of students. From published information you know that the scores are approximately Normal with standard deviation about 6.5. You want your sample mean x¯ to estimate μ with an error of no more than 1.3 point in either direction.(a) What standard deviation (±0.0001) must x¯ have so that 99.7% of all samples give an x¯ within 1.3 point of μ?(b) How large an SRS do you need in order to reduce the standard deviation of x¯ to the value you found in part (a)?

According to data released in 2016, 69% of students in the United States enroll in college directly after high school graduation. Suppose a sample of 232 recent high school graduates is randomly selected. After verifying the conditions for the Central Limit Theorem are met, find the probability that at most 66% enrolled in college directly after high school graduation.

Mr. Chen goes to the post office to buy small and large boxes. He needs at least 4 small boxes. Altogether, he will buy no more than 15 boxes. The post office has 10 small boxes and 9 large boxes in stock. The graph shows the feasible region, where x represents the number of small boxes and y represents the number of large boxes. Which ordered pairs meet all the constraints and make sense in context of the situation? Select each correct answer. (6, 9) (7,10) (8,6) (9,8) Graph of lines and a shaded region on a coordinate plane whose axes are labeled x and y. A solid vertical line passes through 4 comma 0. Another solid vertical line passes through 10 comma 0. A solid horizontal line passes through 9 comma 0. A solid diagonal line passes through 0 comma 15, 4 comma 11, 6 comma 9, and 10 comma 5. The polygon whose vertices are at 4 comma 9, 6 comma 9, 10 comma 5, 10 comma 0, and 4 comma 0 is shaded.
