Question

State the distribution and parameter(s) of the random variable. ALSO write out the support and circle whether the random variable is discrete or continuous. (4 points each). Be sure to label all parameters. Kids at Cumberland Elementary School voted for their favorite lunch item 41% stated that pizza was their favorite one day and asked those students if pizza was their favorite lunch. Let N be the number in Mrs. Quimby's sample who said no. Assume that students' lunch preferences are independent. DISTRIBUTION & PARAMETER(S): ___________ SUPPORT: ____________ Circle one answer: N is DISCRETE N is CONTINUOUS Along a stretch of Interstate 65, cars break down at an average of one every 5 miles. Let B be the number of cars broken down on the side of 1-65 between mile number 158 and mile number 172. Assume that cars break down independently. DISTRIBUTION & PARAMETER(S): ___________ SUPPORT: ____________ Circle one answer B is DISCRETE B is CONTINUOUS

Explanation / Answer

Support Probability is fixed in each trial and independent.

N is Discrete.

9. Poisson distribution parameter (lambda=1/5)

Time-related problem
