Question
High temperatures in a certain city for the month of August follow a uniform distribution over the interval 69F to 84F What is the probability that the high temperature on a day in August exceeds 75F? [Round to four decimal places] 0.6000 You are correct. Your receipt no. is 158-2007 Previous Tries What is the probability that the high temperature on a day in August is within 1.1 standard deviation of mean temperature? [Round to four decimal places] 0.6351 You are correct. Your receipt no. is 158-8531 Previous Tries Above what temperature are 30 % of the daily high temperatures of August? LRound to two dec mal places, 877 Submit Answer Incorrect. Tries 2/5 Previous TriesExplanation / Answer
The lower limit is 69 and upper limit is 84
thus P(x>X)=0.3
thus (84-x)/(84-69)=0.3
thus 84-x=4.5
or x is 84-4.5 =79.5
