'The average value of gasoline purchased by customers ata gas station is 11.5 gallons with a standard deviation of 4.0 gallons. In a sample of 50 randomly selected customers, what is the approximate probability the total amount purchased is at most 600 gallons? 0.81 575 0.19'
Added by Samuel W.
Step 1
We know that the average value of gasoline purchased by customers is 11.5 gallons with a standard deviation of 4.0 gallons. This means that the distribution of gasoline purchased by customers follows a normal distribution with a mean of 11.5 and a standard Show more…

in a sample of 700 gas stations the mean price for regular gasoline at the pump was $2.807 per gallon and the standard deviation was $0.008 per gallon. A random sample size of 55 is drawn from this population what is the probability that the mean price per gallon is less than $2.804? (round to 4 decimal places as needed)

In a sample of 900 gas stations, the mean price of regular gasoline at the pump was $3.746 per gallon and the standard deviation was $0.009 per gallon. A random sample of size 55 is selected from this population. What is the probability that the mean price per gallon is less than $3.742?

Suppose the average cost of a gallon of unleaded fuel at gas stations is $1.897. Assume that the standard deviation of such costs is $0.15. Suppose a random sample of n = 100 gas stations is selected from the population and the cost per gallon of unleaded fuel is determined for each. Consider the "sample mean cost per gallon". What is the approximate probability that the sample has a mean fuel cost between $1.90 and $1.92?
