Six students are randomly selected from the top 15 students of a class to find if their overall score is affected by their response to the first question in the exam. Based on the data given in Table Q.1, answer the subquestions.
Calculate the absolute value of Point Bi-serial correlation coefficient between the response to the first question and overall-marks obtained by the students. (Enter the answer correct to 2 decimal places)
Six students are randomly selected from the top 15 students of a class to find if their overall score is affected by their response to the first question in the exam. Based on the data given in Table Q.1, answer the subquestions.
Are the overall-marks obtained by the selected students strongly influenced by their response to the first question in the exam?
Yes, because the absolute value of Point Bi-serial correlation coefficient is greater than 0.75.
No, because the absolute value of Point Bi-serial correlation coefficient is greater than 0.75.
Yes, because the absolute value of Point Bi-serial correlation coefficient is less than 0.75.
No, because the absolute value of Point Bi-serial correlation coefficient is less than 0.75.
In a manufacturing company, which produces medicine bottles, the chance that the bottles are of good quality is 60%, independent of each other. A sample of 5 bottles is selected for a quality inspection. Based on the given information, answer the subquestions.
What is the probability that exactly 4 bottles are of good quality, given that at least 1 bottle is of good quality?(Enter the answer correct to 2 decimal places)
