(2 points) The amount of time it takes to complete a task is normally distributed with a mean of 34 minutes and a standard deviation of 4 minutes. (2 points) Compute the following probabilities. (2 points each) There is a 42% chance a 22-26 year-old still lives at home.
Please be sure to label your answers and to present them in an organized way. Student 1 got a 40 on an exam where the mean was 30 and the standard deviation was 8 1) On average, from a sample of 160 22-26 year-olds, how many do NOT live at home? (2 points)
1) Find the probability that a randomly selected teen will sleep over 10 hours in a day? (2 points) Student 2 got a 90 on a test where the mean was 88 with a standard deviation of 10. If I take a sample of 24 people how many would I expect to take over 37 minutes to complete the task? 1) p(-0.24 < z < .68)= 2) What is the standard deviation for the problem in 1)? (2 points)
2) If I take a sample of 100 teens, how many of those teens will sleep over 10 hours in a day? (2 points) Show work. 3) What is the normal range for a sample of 160 22-26 year olds who live at home? (2 points)
2) p(0.45 < z < 2.39)=
3) p(z > -1.45)=
