There were 478 orange M&Ms and 206 black M&Ms. Do you believe the population rate of orange M&Ms is 0 N2 0 2.!'3 O No answer text provided. 0 No answer text provided. Question 8 10 pts Suppose the MGM experiment was done using the Julyr 4th M&Ms that only have Red, White, and Blue colors. The total # of M&Ms counted in class was 684. It is believed that probability of a Red M&M = probability of a White M&M = probability of a Blue M&M = 11'3. What is the probability that you would observe at least 244 Red M&Ms?

Let's assume that hemoglobin levels in adult men have a normal distribution with a mean of 15.1 g/dL and a standard deviation of 1.8 gde A random sample of n=40 adult men was taken and their hemoglobin levels measured. Find the approximate probability that the sample mean of these 40 adult men is between 14.8 and 15.3 g/dL? O 0.61 O 0.39 O 0.50 O 0.21 Question 11 10 pts From question 10. Find the probability that the sample mean of these 40 adult men is greater than 15.1 0 0.00 O 0.05 O 0.50 O 1.00
