Extracted text: A random sample of 10 houses in Big Rapids, each of which is heated with natural gas, is selected and the gas (in therms) used during the month of January is determined for each house. The resulting amount of observations are 108, 161, 123, 94, 130, 152, 127, 114, 143, and 104. denote the average gas usage during January by all houses in this area. Compute a point estimate of u. а. Let b. Suppose that there are 10,000 houses in Big Rapids that use natural gas for heating. Let t denote the total amount of gas used by all of these houses during January. Estimate t using the data provided above. What estimator did you use in computing your estimate. Use the data above to estimate p, the proportion of all houses that uses at least 105 therms. Give a point estimate of the population median usage (the middle value in the population of all houses) based on the sample data provided above. What estimator did you use? с. d.
