12.2.18-T Question Help multiple-choice quiz at the beginning of the semester to measure how Suppose a teacher gives her statistics class a fou well prepared they were for the class. The accompanying table shows the number of students who had 0, 1, 2, 3 and 4 questions correct. Using a 0.05, perform a chi-square test to determine if the number of correct answers per student follows the binomial probability od EEB Click the icon to view the data table. What is the null hypothesis, Ho? D A. Ho: The mean number of correct answers per student is not equal to o. O B. Ho: The mean number of correct answers per student is equal to 0. OC Ho: The number of correct answers per student does not follow the binomial probability distribution. D. Ho: The number of correct answers per student follows the binomial probability distribution. What is the alternative hypothesis, H1? 0 A H1 : The number of correct answers per student follows the binomial probability distribution. OB. H:The mean number of correct answers per student is not equal to 0 ?, ?. H1 : The number of correct answers per student does not follow the binomial probability distribution. O D.

Explanation / Answer

Since first and second question is rightly answered, therefore I am answering only 3rd as follows::

Since n is here 4 therefore remaining is p whichi is to be estimated from data but as the data is missing so what we can do is to use formula

p_est=total answered questions/(m*n),

Where n is 4 in our case and m is number of students appeared in test, so if data is known, find total correctly answered questions then proceed with formula as above.
