Use the results of Groth (1992), where researchers conducted a large observational study where n=3647 crossbills were observed in the wild, 1752 of which were right-billed and 1895 of which were left-billed to conduct a z-test. Report your test statistic, p-value, and estimated effect size, each rounded to four decimal places: z-score: p-value: est. effect size:

Solved solution given in the attached document.

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
