Process 1 is an updated process hoped to bring adecrease in assembly time, while Process 2 is the standard process used for several years. Assembly times can vary considerably from worker to worker, and thecompany decides to eliminate this effect by selecting 10 workers at random and timing each worker on each assembly process. Half of the workers are chosen atrandom to use Process 1 first, and the rest use Process 2 first. For each worker and each process, the assembly time (in minutes) is recorded, as shown in thetable below.WorkerProcess 1Process 2Difference(Process 1-Process 2)Send data to calculator1672373 844-8 -23 -2075 96 104 85582 84105-3 -2168292-107 8846378 689 1072796 -5 -739407-1Based on these data, can the company conclude, at the 0.10 level of significance, that the mean assembly time for Process 2 exceeds that of Process 17 Answerthis question by performing a hypothesis test regarding H, (which is u with a letter "d" subscript), the population mean difference in assembly times for the twoprocesses.

Anela is a computer scientist who is formulating a large and complicated program for a type of data processing. Anela has three ways of storing and retrieving data: cloud storage, disk, or hard drive. As an experiment, Anela sets up her program in three different ways: one using cloud storage, one using disks, and the other using a hard drive. Then Anela makes four test runs of this type of data processing on each program. The time required to execute each program is shown in the following table (in minutes). Use a 0.01 level of significance to test the hypothesis that the mean processing time is the same for each method. Hard Drive Cloud Disks 8.7 7.2 7.0 9.3 9.1 6.4 7.9 7.5 9.8 8.0 7.7 8.2

Dr. Barton hypothesizes that if 1st grade students are assigned to practice sight word flashcards for 10 minutes every day for their first semester, they will end up reading more books in their second semester. She creates two groups of 25 students each and gives each group the same sight word flashcards. Group A is assigned to practice with the flashcards for 10 minutes every day for their first semester. Group B is not given this assignment. Each group is tasked with keeping a reading log during their second semester. At the end of 1st grade, Dr. Barton counts how many books each group has read. Group A read 68 books, and Group B read 92 books. The control group is: The independent variable is: The dependent variable is: This study shows that there is a positive correlation between 10 minutes of daily flashcard practice of sight words and the amount of books read. T/F This study is an example of descriptive research. T/F
An Jibble is produced on an assembly line consisting of six workstations. The total work content for one Jibble is 22 minutes based on the following standard times set forth for each station: 1 (4.0 minutes), 2 (6.5 minutes), 3 (4.0 minutes), 4 (2.5 minutes), 5 (2.0 minutes), 6 (3.0 minutes). If this assembly line runs 5 days per week, 8 hours per day and each station operator operates at 120% of standard, how many Jibbles can be produced in a week? a. Greater than or equal to 600 units. b. Greater than or equal to 500 units but less than 600 units. c. Less than 400 units. d. Greater than or equal to 400 units but less than 500 units.
The Phony TV company makes two different types of television sets, OLED and LED, which are assembled by two different assembly lines. When Line One operates it assembles 30 units of the OLED model and 50 units of the LED model per hour. Line Two assembles 40 units of the OLED model and 40 units of the LED model per hour. Let x be the number of hours that Line One operates and y the number of hours Line Two operates. Phony needs to produce at least 3000 units of the OLED model and 4000 units of the LED model to fill an order. (a) Write down the inequalities that describe the assembly constraints. (b) Graph the feasible region determined by these constraints.
A company has three machines, A, B, and C, that are each capable of producing a certain item. However, because of a lack of skilled operators, only two of the machines can be used simultaneously. The following table indicates production over a three-day period, using various combinations of the machines. How long would it take each machine, if used alone, to produce 1000 items?
A stable population of 35,000 birds lives on three islands. Each year 10% of the population on island A migrates to island B, 20% of the population on island B migrates to island C, and 5% of the population on island C migrates to island A. Find the number of birds on each island if the population count on each island does not vary from year to year.
A seamstress works exclusively on one stage of the process of a special garment design. This phase requires exactly half an hour to finish the garment. Every 30 minutes an assistant arrives at the seamstress's table to collect those finished garments and deliver those that require the process (unprocessed garments).The number of raw garments brought by the assistant to the seamstress is uncertain; 30% of the occasions arrive without garments; 50% of the time he wears one garment and 20% of the time he wears 2 garments. The assistant is instructed that there are never more than three unprocessed garments left on the seamstress's table (those that cannot be left are taken to another seamstress). Determine the transition graph and matrix that models the number of raw garments on the seamstress's table just before the assistant arrives.
AJ’s sleep pattern had been fluctuating due to stress and diet, so he started to keep a diary of how many hours he slept each night. On the 4th night after he started the diary, AJ slept 9.4 hours, which was the most sleep he got any night. Gradually, he got less sleep each successive night until, on the 18th night after he started the diary, AJ slept 6.2 hours, which was the least sleep he got any night. After keeping his diary for 6 months, he realized that the number of hours he got each night followed a sinusoidal curve. Let t be the number of nights since he started his diary, and s be how many hours he slept that night. It may be helpful to draw a crude sketch of the sleep time function and label the known t − and s − values on it. POSITIVE or NEGATIVE SIN or COS Maximum s − value = Minimum s − value = ______________ ______________ Middle s − value = ______________ = D Amplitude = ______________ = A ⇒ B = ______________ Given the crude sketch of the height function, the…
The Gotham City Police Department employs 30police officers. Each officer works 5 days per week. Thecrime rate fluctuates with the day of the week, so the numberof police officers required each day depends on which dayof the week it is: Saturday, 28; Sunday, 18; Monday, 18;Tuesday, 24; Wednesday, 25; Thursday, 16; Friday, 21. Thepolice department wants to schedule police officers tominimize the number whose days off are not consecutive.Formulate an LP that will accomplish this goal. (Hint: Havea constraint for each day of the week that ensures that theproper number of officers are not working on the given day.)
An advantage of different emergence patterns for two species of a swarming insect is that they rarely emerge the same year to compete for food. Suppose that type A of the insect has a 5-year emergence cycle and type B of the insect has a 19-year cycle. If both species of the insect emerged during 2011 , when is the next year that both species will emerge during the same year?
