We are interested in assessing the number of ropes a person can jump rope. We have a random sample of 40 people and find that the average person can jump rope 16.4 times with a standard deviation of 3.8. What is the 90% confidence interval for the actual average number of ropes a person can jump? Enter your answers accurate to one decimal place. Can we conclude that the actual average number of ropes a person can jump is at most 17.1? O Yes O No O Not enough information to determine this Beyond representative sampling, what assumptions are needed to satisfy the requirements for this confidence interval? OX ~ normal or n > 30 OX - binomial and at least 5 successes and failures OX - ~ normal andn > 30 OX - binomial, np > 5 and ną > 5 2) Submit Question
