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

Can we conclude that the actual average number of ropes a person can jump is at most 17.1?
- Yes
- No
- Not enough information to determine this
Beyond representative sampling, what assumptions are needed to satisfy the requirements for this confidence interval?
- \( X \sim \) normal or \( n \geq 30 \)
- \( X \sim \) binomial and at least 5 successes and failures
- \( X \sim \) normal and \( n \geq 30 \)
- \( X \sim \) binomial, \( np \geq 5 \) and \( nq \geq 5 \)
