Many companies use sampling to determine whether a batch should be accepted. A (n, c) sampling plan consists of inspecting n randomly selected items from a batch and accepting the batch if c or fewer sampled items are defective. Suppose a company uses a (100, 5) sampling plan to determine whether a batch of 100,000 chips is acceptable.
a)What is the probability of rejecting a batch that has 3% defectives?
b)What is the probability of accepting a batch that has 9% defectives?
If W denotes the total number of spaces one moves under these special conditions, find the mean and standard deviation of W.
The amount ($1.00, $5.00, $10.00, $25.00, or $50.00) promised to each person was determined by randomization. For each person who was sent one of the surveys, The value of the X2 test statistic for testing the hypothesis
Illustrate is the range of values for a coefficient of correlation. Illustrate degree of relationship do values of the correlation coefficient (r)with magnitudes close to 1.00 indicate.
Jeweller desires to know how many of each item to make each week to maximize profit. Create the integer programming model for this problem (written in format similar to way Problems 1 and 2 were presented).
Given that standard deviation process=4.7 and standard deviation gage=3.4, what is the total standard deviation in data from this process?
To determine her blood pressure, Carolyn divides her day into three parts; morning, afternoon, and evening. She then measures her blood pressure at 4 randomly selected times during each part of the day. What type of sampling is used?
What are the mean value and standard deviation of the number among these 15 that are from the second section? What are the mean value and standard deviation of the number of projects not among these first 15 that are from the second section?
Find the percent of a standard Normal model found in the given region. Round to the nearest hundredth of a percent.
If two randoom samples of sizes n1 = 30 and n2 = 36 are selected independently from two populations with mean 78 and 85, and with standard deviations 12 and 15, respectively, then the standard error of the difference between Xbar1 and Xbar2 are eq..
Suppose you found that in doing the hypothesis test, you were able to reject the null hypothesis. What is the most appropriate conclusion to draw?
A comparison group consisted of 5,055 children who had received no such treatment (brothers and sisters of the children who had received radiation treatment).
