In a factory you buy large lots of bolts that has an acceptable quality level of 5% and a rejectable quality level of 10%. When the lots arrive to the factory the quality is controlled using the following double sampling plan: 1st Sample: Pick 30 bolts at random a. If they are all conforming then accept the lot b. If there are 3 or more nonconforming then reject the lot c. Else take a second sample 2nd Sample: Pick 50...

20.) Benford's Law claims that numbers chosen from very large data files tend to have "1" as the first nonzero digit disproportionately often. In fact, research has shown that if you randomly draw a number from a very large data file, the probability of getting a number with "1" as the leading digit is about 0.301. Suppose you are an auditor for a very large corporation. The revenue report involves millions of numbers in a large computer file. Let us...

Examine the frog models 2-5 which represent the 2-cell, 4-cell,.. morula stages. During cleavage, the large zygote (fertilized egg), a single cell, divides (by mitosis) into two cells (2-cell stage); these two cells divide again yielding four (4-cell stage); these four cells divide again yielding eight (8-cell stage); and so on. After dividing a number of times, the embryo is a solid ball of cells, the morula. Just like in the starfish, a cavity (the blastocoel) then becomes visible in...
