N95 masks are made of a polypropylene material that goes through a process where it's meltedand extruded through small-diameter holes into hundreds of tiny fibers that are tangledtogether. The meltblown fibers are randomly oriented with diameters ranging from 1-10micrometers. A quality control engineers measures the diameters of the fibers and testsH:µ=5 versus H:u# 5. If a Type I error is made, what conclusion will be drawnregarding the average diameter of the fibers?(A) The mean fiber diameter is equal to 5 micrometers.(B) The mean fiber diameter is not equal to 5 micrometers.If a Type II error is made in the preceding problem, , what conclusion will be drawnregarding the average diameter of the fibers?(A) The mean fiber diameter is equal to 5 micrometers.(B) The mean fiber diameter is not equal to 5 micrometers

Is the following statement true or false and why: If we do not reject ?0H0, then we conclude that ?1H1 is false. Washers used in a certain application are supposed to have a thickness of 2 millimeters. A quality control engineering measures the thickness for a sample of washers and tests ?0:?=2H0:μ=2 versus ?1:?≠0H1:μ≠0. If a Type I error is made, what conclusion will be drawn regarding the mean washer thickness?

PT. X is an industry engaged in concrete steel with various diameter sizes. The product that is mostly produced is concrete iron with a diameter of 12 mm because it suits the needs of consumers and the current pandemic conditions. During the period from January to December 2019, PT. X is capable of producing as many as 6800 tonnes of units. From the results produced, there is a product defect of 70.4 with the type of product damage, namely overfill (wing), overlap (excessive shape), underfill (kempong) and scratch (beret). In that period, defects were found above the tolerance limit of 2%, namely at week 5 and week 12 of 2.42% and 2.21%. During the production process PT.X has a 2% probability of producing defective products. If you check is 065, then determine:a. P(X=0)b. P(X=1)c. P(X=2)d. P(X≤2)e. P(X≥3)

The amount of oxygen consumption (ml/min) was measured in 6 individuals over two 10- minute periods while sitting with their eyes closed. During the first period, they listen to an exciting adventure story and then again, an hour later while they heard restful music. Based on the results shown, is oxygen consumption different depending on whether it is a story or music one is listening to? The data is in Table 2 and test at an alpha of 0.05. Table 2.
