[3] Situation: In a known hardware store in Pampanga, the manager is interested to know how much on average, their customers spend each visit in the store. Using their records, a 1000 visits were drawn and the customer’s average spending were calculated. From the computation, the mean amount spent of the customers per visit in the store was computed at P3,034.35. This is an example of a: a. Population b. Sample c. Parameter d. Statistic e. Variable

Joan's Nursery specializes in custom-designed landscaping for residential areas. The estimated labor cost associated with a particular landscaping proposal is based on the number of plantings of trees, shrubs, and so on to be used for the project. For cost estimating purposes, managers use two hours of labor time for the planting of a medium- sized tree. Actual times from a sample of 10 plantings during the past month follow (times in hours).

B6. Pinan Insurance Company wants to study the relationship between the amount of fire damage and the distance between the burning house and the nearest fire station. This information will be used in setting rates for insurance coverage. For a sample of 30 claims for the last year, the director of the actuarial department determined the distance from the fire station (x) and the amount of fire damage, in thousands of dollars (y). The MegaStat output is reported below. ANOVA table Source Regression Residual Total Regression output Variables Intercept Distance-X Answer the following questions.
