Abstract
A CERTAIN number of defectives, c, is observed in a sample of n articles drawn at random from a large batch. Nothing else is known about the batch. What inferences can be drawn as to the true but unknown proportion Q of defectives in the lot? In his book An Engineers' Manual of Statistical Methods, Col. L. E. Simon gives several charts which help to answer this question. The basic assumption made is that before sampling one “lot‐fraction‐defective” is as likely as another. The charts are based on the incomplete ?‐function ratio. They make no assumption of homogeneity. From these charts the accompanying alignment charts have been constructed. The degree of accuracy is not, of course, as high as in Simon's charts, but it is thought that it will be high enough for practical purposes.

Abstract
In this chapter, we explore how new technologies, namely, video essays, audio-based feedback, and electronic portfolios, can transform traditional composition curriculum and deepen student learning. We begin by discussing how new technologies connect and enhance learning experiences, especially within writing-intensive courses. For each of the three technologies, we provide a brief literature review, give a local case study, and conclude with suggested applications and related resources.
