I need help with this assignment, would appreciate it if someone can help me!

10. Weights of paper discarded by households each week are normally distributed with a mean xix! z-value formula: : : X-value = 10 + p 0' (round 2 scores to the hundredths) (round x-values to the given value) (round probabilities to three significant digits) According to thepoultrysitecom, the weights of broilers (commercially raised chickens) are approximately normally distributed with a mean of 1397 grams and a standard deviation of 171 grams. Find the probability that: one of these chickens would weigh between 1130 and 1290 grams. 9A. one of these chickens would weigh more than 1500 grams. 9B. . Would you consider it unusual for a broiler to weigh more than 1500 grams? Use a complete sentence or two to explain why or why not. of 23.4 pounds and a standard deviation of 4.2 pounds. Find the highest weight of discarded paper that is in the bottom 25%. You must show the x-value formula. 10. 7. The American Chemical Society believes that there is a 79% chance that in the United States any randomly selected dollar bill is tainted with traces of cocaine. Assume that 15 dollar bills are randomly selected. Find the probability that: A. at the most 5 of them have traces of cocaine. B. fewer than ten of them will have traces of cocaine. C. more than seven of them will have traces of cocaine. 8a. The number of occupants in a randomly chosen car on I-4 during rush hour during morning hours is listed below. Create a probability distribution table to represent the data. Round to the thousandths. Number of Occupants Number of Cars 398 105 31 16 10 2 X P(x ) 8b. USE THE TABLE THAT YOU CREATED ABOVE TO ANSWER THE FOLLOWING QUESTIONS: A. Find the probability that a randomly chosen car had 3 occupants. B. Find the probability that a randomly chosen car had at least 4 occupants. C. Find the probability that a randomly chosen car had at most 3 occupants. D. Find the probability that a randomly chosen car had 2 occupants
