The dependent variable does have effect on the independent variable There is a significant difference between two parameters. In a hypothesis test, the alternative hypothesis is 2 points 19.4 K/s 94 11:18 There is a no significant difference between two parameters. The dependent variable does have effect on the independent variable There is a significant difference between two parameters. In a hypothesis test, the alternative hypothesis is always a statement of equality.

In 1999, the average number of complaints about such things was 0.27 per scheduled flight. Some people believe that airline customers complain more these days about cancelled and late flights. Is this true? What is the appropriate null hypothesis?

The average number of students accessing the library is 80. What is the appropriate alternative hypothesis? A O 56 B/s 94 11:19 Airline passengers understandably do not like it when their flights are canceled or do not leave or arrive on time. In 1999, the average number of complaints about such things was 0.27 per scheduled flight. Some people believe that airline customers complain more these days about cancelled and late flights. Is this true? Assuming that the mean number of complaints about canceled or late flights these days is more than 0.27 per flight, what type of error would be to conclude that these are still 0.27 complaints per flight? 2 points Correct Decision Type II Error None of these Type | Error < O 53 B/s Type | Error 93 11:19 Which of the following is incorrect about formulating hypothesis? 2 points There should always be an equal sign in the null hypothesis The choice of the alternative hypothesis depends on the purpose of the test. The alternative hypothesis usually corresponds to the assumption that no change occurs. The null hypothesis usually corresponds to the assumption that no change occurs. A Type II error can occur when 2 points 56 B/s 93 11:19 corresponds to the assumption that no change occurs. The null hypothesis usually corresponds to the assumption that no change occurs.
