A random sample of 54 students in a statistics class were asked how many hours they had studied before a statistics test.The linear model equation below describes the relationship between the mean test mark and the hours of study.mark == 4.04 ++ 0.27 ×× studyBased on this linear model, which of the following statements is correct?Choose ONE:A student who gets one more mark than another in the test is expected to have studied for 4.04 more hours.A student who did not study would be expected to get 4.04 marks in the test.A student who got zero marks in the test is expected to have studied for 4.04 hours.A student who studies 1 hour more than another is expected to get 4.04 more marks in the test.

Teacher Joy conducted a census in her class, and she found out that the average time that her students devote to studying is 2.25 hours, their average height is 147 cm, and a random sample of 10 students got an average of 87% in their latest quiz.Which of the given numbers is a sample?*1 point10 Students2.25 Hours147 cm87%

In a test, the average marks of five students was found to be 48. Later it was discovered that the marks of one student was misread as 32 instead of 67. Find the correct average?

If the average marks of two batches of 55 and 45 students respectively is 50 and 60, then the average marks of all the students is:a.54.5b.55c.56.8d.53

Data was collected on 50 HIT students showing the average amount of time spent studying daily during their first and fourth years. Do students study more or less in their fourth year compared to their first?In order to answer this question, which of the following test procedures is most apprpriate?

In a Statistics test, the average mark is 82 and the standard deviation is 5. All the students from 88 marks up to 94 marks will receive a B grade. If the marks have a normal distribution and 8 students receive B grade, determine the total number of students who sat for the test.
