In 1983, Daniel Kahneman and Amos Tversky posed the now famous "Linda" problem, asking participants to rank the probabilities of certain statements after reading a short description. Replicating this experiment, a statistics teacher (named Mr. Zak) constructed a similar question about a young woman named "Wendy." Students read a short description of Wendy and were asked to determine which statement is more probable: (A) "Wendy is currently a public high school teacher," or (B) "Wendy is currently a public high school teacher and rides her bike to work most days." Based on Kahneman's results, this statistics teacher hypothesized that 30% of well-educated high school students would choose option B. As it turned out 68 students (in 2019) participated in the experiment and 25 chose option B. If we presume the 68 students are a random sample from well-educated high school and all conditions for inference are satisfied, what is the test statistic for a test of significance against the teacher's hypothesis? 1.217 O 1.157 O 1.374 O 2.059 2.378

Question
In 1983, Daniel Kahneman and Amos Tversky posed the now famous
"Linda" problem, asking participants to rank the probabilities of certain
statements after reading a short description. Replicating this experiment,
a statistics teacher (named Mr. Zak) constructed a similar question about
a young woman named "Wendy." Students read a short description of
Wendy and were asked to determine which statement is more probable:
(A) "Wendy is currently a public high school teacher," or (B) "Wendy is
currently a public high school teacher and rides her bike to work most
days." Based on Kahneman's results, this statistics teacher hypothesized
that 30% of well-educated high school students would choose option B.
As it turned out 68 students (in 2019) participated in the experiment and
25 chose option B. If we presume the 68 students are a random sample
from well-educated high school and all conditions for inference are
satisfied, what is the test statistic for a test of significance against the
teacher's hypothesis?
1.217
O 1.157
O 1.374
O 2.059
O 2.378
