So you rejected this null hypothesis of 80% even though it's actually true. You believe that if you get lost in a desert, there is only a 3.14% chance of survival. You take a sample and find that 2.98% of your sample survived when lost in the dessert, and so you didn't reject your null hypothesis. However, in reality, there is a 40% chance of survival.arrow_forwardAd Effectiveness Viewing Audience VOD D4 + General TV Made Me Want To Visit The Brand Website Yes 409 194 No 148 90 n Iarrow_forward
- A textbook publisher claims that 75% of college students enrolled in a course that uses their textbooks pass the class. One professor thinks the proportion is actually higher. He surveys 111 students in classes that use a textbook from the textbook publisher and finds the 92 of those students ultimately pass the class.
