What is the probability it will take less than 8.50 hours to rebuild a Ford V10 engine? ANSWER places, using conventional rounding rules) What is the probability it will take between 9.50 and 11.75 hours to rebuild a Ford V10? ANSWER: places, using conventional rounding rules) What is the standard deviation of this probability distribution? ANSWER: Report your answer to conventional rounding rules) FS io 4Explanation / Answer
1. P(X)= 1/(b-a) for X between (a,b)
P(X)= 1/(13-7)= 1/6
2. Probability will remain the same as in (1) as it is rectangular probability distribution. The value is same throughout the range in uniform distribution.
3. SD= Sq. Root Variance= (b-a)/(Sq. Root12)=Sq.Root 3= 1.732
