The U.S. Geological Survey compiled historical data about Old Faithful Geyser (Yellowstone National Park) from 1870 to 1987. Let x1 be a random variable that represents the time interval (in minutes) between Old Faithful eruptions for the years 1948 to 1952. Based on 8860 observations, the sample mean interval was x1 = 61.4 minutes. Let x2 be a random variable that represents the time interval in minutes between Old Faithful eruptions for the years 1983 to 1987.

The US Geological Survey complied historical data about Old Faithful Geyser from 1870 to 1987. Let x1 be a random variable that represents the time interval (in minutes) between Old Faithful eruptions for the years 1949 to 1952. Based on 8840 observations, the sample mean interval was x1=65.0 minutes. Let x2 be a random variable that represents the time interval in minutes between Old Faithful eruptions for the years 1983 to 1987. Based in 24404 observations the sample mean time interval was x2=71.2 minutes. Historical data suggest that o1= 8.14 minutes and o2= 11.78 minutes.

Round your final answer to 3 decimal places.) ux = ox^2 = σχ (b) Calculate the intervals [Uy + 20x] and [Uy + 30x]. Find the probability that x will be inside each of these intervals. Hint: When calculating probability, round up the lower interval to next whole number and round down the upper interval to the previous whole number. (Use the value for standard deviation from part a. Round all your answers to 4 decimal places. Negative amounts should be indicated by a minus sign.) [ux + 2ox] [px + 3ox] SX S
