Question
illan Learning Equip male and female students with a small device that secretly records sound for a random 30 seconds during each 12.5-minute period over two days. Count the words each subject speaks during each recording period, and from this, estimate how many words per day each subject speaks. The published report includes a table summarizing six such studies. Two of the six are given. Study 1 2 Sample Size Women 56 27 Men 56 1 20 Estimated Average Number (SD) of Words Spoken per Day Women 16,177 (7520) 16,496 (7914) Men 16,569 (9108) 12,867 (8343) Readers are supposed to understand that, for example, the 56 women in the first study had x = 16,177 and s = 7520. It is commonly thought that women talk more than men. Does either of the two samples support this idea? Matthias R. Mehl et al., "Are women really more talkative than men?" Science, 317 (2007), p. 82. What degrees of freedom does Option 2 use to get a conservative P-value for each study? Give your answers as whole numbers.
