White Rock is trying to determine an acceptance sampling plan for parts Y500 and P2000, both of which are purchased from suppliers . For part P2000, management would like to be 95% sure of rejecting shipments that have more than 3% defectives, but wants to accept shipments with less than 1% defectives 90% of the time. Answer each of the following questions. For each question, use at least four decimal places when doing your calculations, but then ROUND OFF your answer to the number of decimal places specified for each question. What is the implied AQL for part P2000 based on the information given (round to 2 decimal places) ? What is the implied LTPD for part P2000 based on the information given (round to 2 decimal places) ? What is the implied probability of a Type II error for part P2000 based on the information given(round to 2 decimal places) ?

The executives at Sandbachian, inc., having recently solved their widget crisis, have another problem with one of their products. Many cities are sending complaints that their manhole covers are defective and people are falling into the sewers. The workers took a random sample of 800 manhole covers and found that 40 of them were defective. What is the 95% CI for p, the true proportion of defective manhole covers, based on this sample?
Workers at a particular mining site receive an average of 35 days paid vacation, which is lower than the national average. The manager of this plant is under pressure from a local union to increase the amount of paid time off. However, he does not want to give more days off to the workers because that would be costly. Instead he decides he should fire 10 employees in such a way as to raise the average number of days off that are reported by his employees. In order to achieve this goal, should he fire employees who have the most number of days off, least number of days off, or those who have about the average number of days off? a. He should fire employees who have the most number of days off. b. No matter who he fires, it will not increase the amount of paid time off. c. He should fire employees who have the average number of days off. d. He should fire employees who have the least number of days off.

The state education commission wants to estimate the fraction of tenth-grade students that have reading skills at or below the eighth-grade level. Step 1 of 2 : Suppose a sample of 1134 tenth graders is drawn. Of the students sampled, 226 read at or below the eighth-grade level. Using the data, estimate the proportion of tenth graders reading at or below the eighth-grade level. Enter your answer as a fraction or a decimal number rounded to three decimal places.
For the scenarios below, determine which sampling method was used (simple random, cluster, convenience, stratified, systematic), and briefly state how you were able to identify the type of sampling being used. Please note: each sampling method will be used only once. -A student surveys 30 people who happen to be on campus at 1:00 pm on a Monday. -Students are divided into groups by number of years at the college, and then a simple random sample is drawn from each group. -Students are divided into groups based on income level, 3 income levels are randomly selected, and all students within the selected income groups are surveyed. -50 students are selected by using their student ID numbers, and a random number generator. -Students are selected by selecting every 10th name off of a list of all current students at STS.
Suppose that a national poll of 300 registered Republicans was conducted this week and 165 stated that they preferred Donald Trump to be the 2024 Republican candidate for President. (a) What is the sample proportion of registered Republicans preferred Donald Trump to be their candidate (to 2 decimal places)? (b) For the sample proportion derived from the poll (in part (a)), what is the standard error of the proportion (to 4 decimal places)? (Preserve many decimal places until you present only 4 decimal places for the final answer.) (c) If I wanted to construct a 90% confidence interval of the proportion of registered Republicans who prefer Donald Trump's candidacy based on this poll, what critical z would I use?

The state education commission wants to estimate the fraction of tenth grade students that have reading skills at or below the eighth grade level. Step 1 of 2: Suppose a sample of 333 tenth graders is drawn. Of the students sampled, 260 read above the eighth grade level. Using the data, estimate the proportion of tenth graders reading at or below the eighth grade level. Enter your answer as a fraction or a decimal number rounded to three decimal places. Step 2 of 2: Suppose a sample of 333 tenth graders is drawn. Of the students sampled, 260 read above the eighth grade level. Using the data, construct the 80% confidence interval for the population proportion of tenth graders reading at or below the eighth grade level. Round your answers to three decimal places.
