Question

Do students whose native language is not English pick up on authors’ efforts to use humor in illustrating points in textbooks? Students at one university were shown a passage from a textbook that was meant to be humorous. Of the 211 students in the study where English was not their native language, 118 thought the passage was humorous. Of the 206 students in the study where English was their native language, 155 thought the passage was humorous. Analyze these data to answer the research question. Note that this data set is from only one passage of many others used to examine humor and language for the study. The data set is courtesy of Melody Geddert, English Language Studies, Kwantlen Polytechnic University.

Answer 1

Test and CI for Two Proportions

Sample    X    N Sample p
1       118 211 0.559242
2       155 206 0.752427

Difference = p (1) - p (2)
Estimate for difference: -0.193185
95% CI for difference: (-0.282412, -0.103959)
Test for difference = 0 (vs ≠ 0): Z = -4.15 P-Value = 0.000

since p-value = 0.000 < 0.05

we reject the null hypothesis

there is sufficient evidence that the proportions are different
