Suppose you want to test Ho: p=0.4 3 points versus Ha: p > 0.40 at the 0.05 level of significance. What would your conclusion be? O Reject Ho. O Accept Ha. O Fail to reject Ho. None of these The process of using sample statistics 3 points to draw conclusions about a true population parameters is called O statistical inference O the scientific method O sampling O descriptive statisticsResearchers are concerned about the 3 points impact of students working while they are enrolled in classes, and they'd like to know if students work too much and therefore are spending less time on their classes than they should be. First, the researchers need to find out, on average, how many hours a week students are working. They know from previous studies that the standard deviation of this variable is about 5 hours. A survey of 200 students provides a sample mean of 7.10 hours worked. What is a 95% confidence interval based on this sample? O (6.10, 8.10) O (6.41, 7.79) O (6.57, 7.63) O (7.10, 8.48)Researchers are concerned about the 3 Points impact of students working while they are enrolled in classes, and they'd like to know if students work too much and therefore are spending less time on their classes than they should he. First, the researchers need to find out, on average. how many hours a week students are working. They know from previous studies that the standard deviation of this variable is about 5 hours. Suppose that this confidence interval was (6.82. 133). Which of these is a valid interpretation of this confidence intervai'? There is a 95% probability that the true 0 average number of hours worked by all UF students is between 6.32 and 138 hours There is a 95% probabilitythat a randomly 0 selected student worked between 6.32 and 133 hours. We are 95% condent that the average 0 number of hours worked by students in our sample is between 5-32 and 138 hours. We are 95% condent that the average 0 number of hours worked by all UF students is between 5.32 and 138 hours. CHOOSE THE CORRECT ANSWER THEN EXPLAIN. FOR COMPUTATION, SHOW YOUR COMPLETE SOLUTION. MUCH BETTER IF YOU'LL WRITE IT ON A PAPER
