To what extent do syntax textbooks, which analyze the structure of sentences, illustrate gender bias? A study of this question sampled sentences from 10 texts. One part of the study examined the use of the words "girl," "boy," "man," and "woman." We will call the first two wordsjuvenileand the last twoadult. Is the proportion of female references that are juvenile (girl) equal to the proportion of male references that are juvenile (boy)? Here are data from one of the texts:

Gender n X(juvenile)

Female 61 49

Male 133 50

(a) Find the proportion of juvenile references for females and its standard error. Do the same for the males. (Round your answers to three decimal places.)p_F=

SE_F=

p_M=

SE_M=

(b) Give a 90% confidence interval for the difference. (Do not use rounded values. Round your final answers to three decimal places.)

,

(c) Use a test of significance to examine whether the two proportions are equal. (Usep_Fp_M.Round your value forzto two decimal places and round yourP-value to four decimal places.)z=P-value=

State your conclusion.

There is sufficient evidence to conclude that the two proportions are different.

There is not sufficient evidence to conclude that the two proportions are different.
