It is claimed that in a case of auto parts, less than 10% are defective. A sample of 400 parts is examined and 50 are found to be defective. What is the alternate hypothesis?

It is claimed that in a bushel of peaches less than ten percent are defective. A sample of 400 peaches is examined and 50 are found to be defective. What is the critical value for Z if you were testing the hypothesis with α = 0.025 1.96 ±1.65 -1.96 -1.65
5. It is claimed that in a bushel of peaches, less than ten percent are defective. A sample of 400 peaches is examined and 50 are found to be defective. If ? = 0.025,what will be the decision? Show full working because points will be awarded for how you arrived at your answer, based on the clarity and correctness of yourresponse.A. Fail to reject the null and conclude the defects are not greater than 10%B. Reject the null and conclude...
A researcher is testing the hypothesis that more than 5% of parts are defective using a random sample of 498 parts. If the z test statistic is 3.9271, then how many parts were defective in the sample? (Record your answer accurate to the nearest integer with standard rounding.)
If a researcher believed that the average young adult (under age 30) carries less than $10 in cash with them, then the Null Hypothesis for the hypothesis test should be: a) The mean is less than $10 b) The mean is not equal to $10 c) The mean is equal $10 d) The mean is at most $10 For a hypothesis test, a sample is gathered. The sample mean and P-value are found. What is the meaning of the P-value?...
A bin of 50 parts contains 5 that are defective. A sample of 10 parts is selected at random, without replacement. (a) How many different samples of size 10 are there that contain at least three defective parts? (b) How many ways to obtain a sample of 10 parts from the bin of 50? (c) What is the probability of obtaining at least three defectives in a sample of 10 parts?
Suppose 4 out of 40 batteries shipped to an auto parts store are defective. A fleet manager then buys 6 of the batteries from the store. What is the probability that at least 3 of the batteries purchased by the fleet manager are defective?
a bin of 50 parts contains five that are defective. a sample of three parts is selected at random without placement. a. determine the probability that at least two parts in the sample are defective. b. given that at least two parts in the sample are defective, what is the probability that all three are defective
Company records show that the proportion of defective parts has historically been 5%, however a quality control engineer believes that due to budget cuts these numbers have increased. To test this claim a random sample of N = 15 parts will be taken and if more than two defective parts are found the inspector will conclude that the proportion of defective parts has increases. If the true probability of a defective part is in fact p = 10% what is...
Five percent (0.05) of the parts produced by a machine are defective. Twenty(20) parts are selected at random for study. A. what is the probability that more than 4 parts are defective? B. what is the probability that exactly 3 parts are defective? C. what is the expected number of defective parts in the sample? D. What is the variance and standard deviation of defective parts in the sample?
A batch of 30 intrinsic semiconductors contains 10% defective parts. A sample of 10 is drawn at random. X = the number of defective parts in the sample. Determine the probability in the sample (X).
