Supplier on-time delivery performance is critical to enabling the buyer's organization to meet its customer service commitments. Therefore, monitoring supplier delivery times is critical. Based on a great deal of historical data, a manufacturer of personal computers finds for one of its just-in-time suppliers that the delivery times are well approximated by the normal distribution with mean 45.8 minutes and standard deviation 13.4 minutes. A random sample of 7 deliveries is selected. a) What is the probability that a particular delivery will arrive in less than one hour? Round your answer to four decimal places. b) What is the probability that the mean time of 7 deliveries will exceed one hour? Round your answer to four decimal places. c) Between what two times do the middle 60% of the average delivery times fall? and Round your answers to two decimal places. d) What is the probability that, in a random sample of 7 deliveries, more than three will arrive in less than an hour? Round your answer to four decimal places.

This is the dataset of the difference between after treatment lab scores and before treatment lab scores. alfa(significance level) is 0,05.

question ) You suspect that the treatment has decreased their lab scores. Conduct a hypothesis test
to see if the lab score has decreased significantly. (minus means it is decreased)

Please, I need somebody to correct my writing.

In chapter one, Marji is 10 years old in 1980. In 1980, the new regime in Iran made it necessary for women to wear the veil. They also separated the schools between male and female. Marji was told us that she wanted to be a prophet. On the other hand, she was told her parents she will be a doctor. In chapter two, the new regime burned a movie theater with a pack of people in it. Marji was wanted to join the demonstration that's being arranged against the regime, but her parents won't let her go. In chapter three, her dad described to her how the king actually came to the throne: The British placed him there to take control of Iran's oil. In chapter four, her grandpa served as prime minister, but he was denied by the new regime. One night, the family has waited a long time for Marji's father to come home from a demonstration. Marji was though he has died. When he came back, he was described what happened at the demonstration, but Marji is too young to understand. She was decideed to teach herself to understand what her father said, and she was started reading lots of books. In chapter five, Marji reads and realizes that the biggest problem is the divide between social groups. She has recognized the first divide when her maid, Mehri, falls in love with the neighbor but she was denied to continue with him because she was from the lower level than he. In chapter six, time for another regime change in Iran. People are excited, but Marji's parents know better than to expect any peace. Marji bullies a kid in school because his father was with the king police and he has killed the people. After her mom talked with her, Marji realized that she has to learn to forgive. In chapter seven, the political hostages are released, and two of the released hostages are friends of the family. They invite Mohsen and Siamak to their house, and Mohsen told them about the painful torture he suffered. later, she feels overwhelmed and tries to get a peace with her mom and God. In chapter eight, Marji is sad because of her dad never arrest. "My father was not a hero", she said. unfortunately, her Uncle Anoosh was arrested. His story is scary. When he returns to Iran, he is captured and jailed for nine years. Marji believes that is awesome. In chapter nine, while Uncle Anoosh stays in their house, Marji hears all the political discussion. It's like watching a foreign TV shows without the subtitles: She can understand some titles, but not the specifics details. One day, Marji comes back from school to find Anoosh left. Marji's dad said: Anoosh was arrested, and he's allowed to talk to one person in the prison, and he wants to talk to her. When she visited him, he tells her, "You are the little girl I always wanted to have", and he gives her a little swan that he made to match the one he gave her before. He then calls her the "star of his life". It's really effective words because it's the last time she meets with him. In chapter ten, Iran starts shutting down. They shut down the U.S. embassy and the universities. One day, she attends her parents to a demonstration, where she sees someone stabbed in the leg. That's the last demonstration they go to. They take a vacation to Spain. It's nice, but when they return, they know that a new war is starting, this time with IRAQ. In chapter eleven, Marji was with her fathers' at his office when Iraqi fighter struck Tehran. At school, Marji heard that a friend's dad is a fighter pilot for Iran. He died in the battle. Marji was told her friend that her father is a hero, and she should be proud. The friend responds: "I wish he were alive and in jail rather than dead and a hero". In chapter 12, Iranian has cleared out the supermarket shelves. Marji's mother's friend's house is destroyed when Iraqi fighter bomb Tehran, so she and her family became refugees at Marji's family. They go out shopping one day, and they overhear two women talking about "the refugees," which Mali (Marji's mom's friend) and her family. These women say, "Southern women are all whores". Marji and her family are ashamed to be "spat upon by their own kind".

Tisla Motors needs to select an assembly line for producing their new SUV. They have two options:

Option A is a highly automated assembly line that has a large up-front cost but low maintenance cost over the years. This option will cost $9 million today with a yearly operating cost of $2 million. The assembly line will last for 5 years and be sold for $5 million in 5 years.

Option B is a cheaper alternative with less technology, a longer life, but higher operating costs. This option will cost $6 million today with an annual operating cost of $3 million. This assembly line will last for 8 years and be sold for $1 million in 8 years.

The firm’s cost of capital is 12%. Assume a tax rate of zero percent. The equivalent annual cost (EAC) of better option should be $_______ million.

a. 3.409

b. 3.552

c. 3.710

d. 3.867

e. 4.127

LIFO Perpetual Inventory

The beginning inventory of merchandise at Dunne Co. and data on purchases and sales for a three-month period ending June 30 are as follows:

Required:

1. Record the inventory, purchases, and cost of merchandise sold data in a perpetual inventory record similar to the one illustrated in Exhibit 4, using the last-in, first-out method. Under LIFO, if units are in inventory at two different costs, enter the units with the HIGHER unit cost first in the Cost of Merchandise Sold Unit Cost column and LOWER unit cost first in the Inventory Unit Cost column.

2. Determine the total sales, the total cost of merchandise sold, and the gross profit from sales for the period.

3. Determine the ending inventory cost on June 30.

Which of the follwoing for a-j is true? The following information is available for an MRP problem. The BOM file shows that Product A is made of one unit of Part B, two units of Part C, and three units of Part D. Part C is made of two units of Part E and three units of Part F. Checking the correct statements results in earning credits, while checking incorrect statements results in losing a half of a correct statement.

Recall from Example 1 that whenever Suzan sees a bag of marbles, she grabs a handful at random. She has seen a bag containing four red marbles, two green ones, four white ones, and three purple ones. She grabs eight of them. Find the probability of the following event, expressing it as a fraction in lowest terms. HINT [See Example 1.] She has all the red ones.
