Question

Eating Bratwurst is not so popular among Turks living in Berlin. But Salim Salam claims that more than 15% of the Turks eat Bratwurst regularly. Mr. Salam asked 40 Turks picked at random, and 12 confirmed (to confirm – doğrulamak) that they eat Bratwurst regularly. What is the probability that between 3 and 6 out of 35 randomly selected Turks eat Bratwurst regularly if indeed 15% of them, in general, do so? (3 and 6 are included). You must use the normal approximation. To calculate this probability, you will first have to calculate two z-scores, and then find the area between them. Write your answers with two digits after the decimal point for the z-scores, and with four digits after the decimal point for probability. Z1= ____ , Z2 = _____ , Probability = _____
