6. A single sample plan for defectives is required to have (p,PA) = (AQL = 0.01,1 -α = 0.95) and(RQL = 0.05,ẞ= 0.10).a. Determine the sample size and acceptance number for the attribute sampling plan that meets theserequirements.b. Determine the sample size and critical k factor for a variables sampling plan using two-sided speclimit. Assume that standard deviation is known and that the process noise is normal.c. Repeat part b but assume that the standard deviation is not known.

To solve this problem, we'll design three sampling plans: an attribute sampling plan and two…

6. Total plasma volume is important in determining the required plasma component in blood replacement therapy. Suppose male firefighters are tested and their plasma volume standard deviation is 7.50 ml/kg. Find the sample size necessary for a 93% confidence level with an error of estimate E-2.50 for the mean plasma volume in male firefighters.
A population consists off the four numbers 2,4,6,7,10 with mean = 5.8 and vairance = 2.7129. Consider all the possible samples of size three which can be drawn with from replacement from the population. What is the mean of the sampling distribution of x? What is the standard error of the samling distribution of x?
a random sample of 30 students IQ scores have a mean score of 112.5. if the mean population IQ is 100 with a standard deviation of 15, assuming a to tail sampling. Determine the confidence interval of the sampling distribution, determine the variance of sampling distribution, is the mean IQ of the sample is within the acceptable values?
the central limit theorem informs the numerator of the z- score for the sample means equation. true or false?
7. Sample size Assume the population is infinite, The travel-to-work time for residents of the 15 largest cities in the United States is reported in the 2003 Information Please Almanac. Suppose that a preliminary simple random sample of residents of San Francisco is used to develop a planning value of 6.25 minutes for the population standard deviation. a. If we want to estimate the population mean travel-to-work time for San Francisco resi- dents with a margin of error of 2 minutes, what sample size should be used? Assume 95% confidence. b. If we want to estimate the population mean travel-to-work time for San Francisco resi- dents with a margin of error of 1 minute, what sample size should be used? Assume 95% confidence.
The gestation period of humans follows a normal distribution with a mean of 266 days and standard deviation of 16 days. If random samples of 15 pregnancies are studied, what is the mean and standard error of th sampling distribution of the sample mean? mean of the sampling distribution [ Choose ] standard error of the sampling distribution [ Choose ]
A population consisting of Reg. Nos. 2, 3, 5, 6, 7. • Draw all possible sample of size 2 without replacement from this population. • Construct sampling distribution of sample proportion of odd No. • Find expected mean and standard error from this sampling distribution. • Also verify the results.
Many college graduates who are employed full-time have longer than 40-hour work weeks. Suppose that we wish to estimate the mean number of hours, μ, worked per week by college graduates employed full-time. We'll choose a random sample of college graduates employed full-time and use the mean of this sample to estimate μ. Assuming that the standard deviation of the number of hours worked by college graduates is 6.10 hours per week, what is the minimum sample size needed for us to be 95% confident that our estimate is within 1.5 hours per week of μ? Carry the intermediate computations to at least three decimal places. Compose the answer as a whole number (and make sure that it is the minimum whole number that satisfies the requirements).
