An organization monitors many aspects of elementary and secondary education in a very large couintry. Their 1997 numbers are often used as a baseline to assess changes. In 1997, 34% of students had not been ahsent from school even once during the previous month. In the 2002 survey, responses from 7295 randomly selected students showed that this figure had slipped to 3396 . Officials would, of course, be concerned if student attendance were deelining. Do these figures give evidence of a change in student attendance? Consider an event to be rare if its probability of occurring is less than 0.10. Complete parts a-e below. a) Write the appropriate hypotheses. Let p be the poputation proportion of students who have not been absent from school even once during the pastmonth. H0:P=HA:p= (Type integers or defimals. Do not round.) b) Check the assumptions and conditions. The Randomization Condition reasonably be assumed to be satisfied. The 10%6 Condition reasonably be assumed to be satistiod. The Success/Failure Condition satsfied. c) Perform the test and find the P-value. The test statistic is (Round to two decimal plaices as needed.).
