Suppose the average price of a gallon of unleaded fuel at gas stations across the country is $2.897. Assume that the standard deviation of these prices is $0.21 per gallon. A random sample of 100 gas stations is drawnfrom parts of the country. Let X denote the average price of a gallon of unleaded fuel at the gas stations in the sample.(a) What is the standard deviation of X ?Answer: [Select](b) What is the probability that X is between $2.90 and $2.93?Answer: [Select]

Probability is the chance that an unsure event will occur with this probability. Basically, the…
