以下是心統的題幹與問題
想請問第以下兩題是否有計算錯誤？

1.
Any of you who have listened to children tell stories will recognize that, unlike adults, they tend to
recall stories as a sequence of actions rather than as an overall plot. Their descriptions of a movie are
filled with the phrase "and then...." An experimenter with supreme patience asked 50 children to tell her
about a given movie. Among other variables, she counted the number of "and then..." statements, which
is the dependent variable. The data follow:
18 15 22 19 18 17 18 20 17 12 16 16 17 21 23 18 20 21 20 20
15 18 17 19 20 23 22 10 17 19 19 21 20 18 18 24 11 19 31 16
17 15 19 20 18 18 40 18 19 16
簡單翻譯:心理學家請小孩描述電影情節,並記錄他們使用「然後」的次數,50 位小孩的次數
如上。

e. The number of times a kid said “and then...” is just above 70% of the participants. What's the
corresponding z score? What's the corresponding T score?有一人念「然後」的次數多於 70%的
參與者,若將其分數轉成z分數,應是多少?若轉成T分數,應是多少?(5%)
20-18.9
4.5 : 0.25
J= 10×0.25 +50= 52.5
