9) A group of 40 students in an English class is given a paragraph and asked to memorized as much as possible. Their retention is then measured on a scale from 1 to 99. The contention being tested is that the average student will score 70 on the scale with a standard deviation of 11.62. it is assumed that the distribution of scores is normal. This grouped scores a mean of 66.93. Using the 0.10 level of significance, does this result prove contention? Solution: I. Statement of the Hypothesis: Но H1 II. Statistical Test: III. Level of Significance and Critical Value: IV. Computed value of Z:
