- ThabksFalling coconuts kill over 150 people each year, which is more than the number of people who die each year from shark attacks. An independent study is conducted to validate this claim and to educate people about coconut safety. The study randomly selected 10 years from the past 100 years in which records have been kept for coconut deaths. We want to estimate the true mean number of deaths that can be attributed to falling coconuts annually with 95% confidence. Are the conditions for calculating a confidence interval for u met in this case? Explain. No. The Random condition is not met and the Normal/Large Sample condition is not met. Yes! Both the Random and Normal/Large Sample conditions are met. We do not have enough information provided to determine if both of the conditions are met. No. The Normal/Large Sample condition is met, but the Random condition is not met. No. The Random condition is met, but the Normal/Large Sample condition is not met.Help please!
