A vendor is supplying 90 parts. Suppose that 10 of them are defective. We take a sample of size 6. At least 90% of the time the sample will contain k or fewer items. What is the smallest value of K?Give numerical answers as integers or decimals rounded to four decimal places.1. Notice here that the population size N = is known. We also know that M=. Let X be the number ofofthese are defective. We are taking a sample of size n3=defective items in the sample. Xhas a distribtuion.2. Notice that this is an inverse probability problem. We want to know the smallest value ofk where P(X s k) 0.9. Use Dr. Jackson's appropriate calculator function or programto solve this problem. The calculator returns the following portion of the CDF table.cdf(X)3. At least 90% of the time the sample will containk or fewer items.

What is the general relationship, if any, between the sample size and the margin of error? OA. Increasing the sample size by a factor M results in the margin of error decreasing by a factor of M2 O B. Increasing the sample size by a factor M results in the margin of error decreasing by a factor of 1 M 1 OC. Increasing the sample size by a factor M results in the margin of error decreasing by a factor of VM O D. There is no relationship between the sample size and the margin of error.
