Question

lFor the question below, answer cach question and, also, match the described arca, probability, score, or critical value with the appropriate StatCrunch output choice SlaiCrunch ounipul choices are prorided on the ned page of the eam Assume that patient waiting times at doctors' offices are uniformly distributed between 15 and 28 minutes. Find the probability that a randomly sclected paticnt has a waiting time between 20 and 25 minutes. a. Report the probability here: Indicate which StatCrunch output corresponds to the above: b. Assume that bone density scores follow the standard normal distribution with mean 0 and standard deviation 1. l ind the area to the right of a bone density score of 1.26 of a bone density score of Report the area her: Indicate which StatCrunch output corresponds to the above: Find the critical value z,/2 that corresponds to a 92% confidence level. C. Report the critical value here: Indicate which StaCrunch output corresponds to the above:--

Explanation / Answer

a)Probability = (25-20)/(28-15)=5/13

b)Z= (1.26-0)/1=1

P(z>1)=0.158655

c) Z for 92% confidence level means that

P(z<Z)=[1-92% ]/2=0.04

Z=1.750686
