Answer:
Activity expected duration = 2.333
Explanation:
Given:
Optimistic (a) = 1
Most likely (m) = 2
Pessimistic (b) = 5
Activity’s expected duration = ?
Computation of Activity expected duration:

Activity expected duration = [1 + 4(2) + 5] / 6
Activity expected duration = [1 + 8 + 5] / 6
Activity expected duration = [14] / 6
Activity expected duration = 2.333

Answer:
The Diary Survey.
Explanation:
"The other national data sources and its publishing period are highlighted in the next cite:
"The Consumer Expenditure Survey (CE) is a nationwide household survey conducted by the U.S. Bureau of Labor Statistics (BLS) to find out how Americans spend their money. It is the only federal government survey that provides information on the complete range of consumers’ expenditures as well as their incomes and demographic characteristics. BLS publishes 12-month estimates of consumer expenditures twice a year with the estimates summarized by various income levels and household characteristics. BLS also produces annual public-use microdata files to help researchers analyze the data in more detail.
The CE consists of estimates derived from two separate surveys, the Interview Survey and the Diary Survey. The Quarterly Interview Survey is designed to collect data on large and recurring expenditures that consumers can be expected to recall for a period of 3 months or longer, such as rent and utilities, and the Diary Survey is designed to collect data on small, frequently purchased items, including most food and clothing. Together, the data from the two surveys cover the complete range of consumers’ expenditures. CE data are collected for BLS by the U.S. Census Bureau."

Answer:
is available to all and cannot be denied to anyone. 
Explanation:
Public goods are both nonexcludable and nonrivalrous. This means that everyone is entitled to use them and when someone is using them it doesn't mean others can't use them at the same time. Of course there is always a limit to the capacity of their use, like roads can only be used by certain amount of cars. 
For this particular characteristic of public goods is that private firms don't offer them. Private firms' main concern is making the largest possible profit and public goods usually aren't profitable. That is why the government has to provide public goods since no one else will.
