The manager at a golf course found that the population mean length of the holes at the golf courses is 415.9 yd. In this context, is the number 415.9 a parameter or a statistic?
Answer: The number 415.9 is a parameter because it represents the population characteristic.
<u>Explanation:</u>
Parameter: Parameters are numbers that summarize the entire population. For example the population mean summarizes the entire population, similarly population standard deviation describes the characteristic of entire population.
Statistic: Statistic are numbers that describes the sample. For example, the sample mean summarizes the sample which is drawn from the population, similarly the sample standard deviation describes the characteristic of sample.
Therefore, the population mean length of the holes at the golf courses (415.9 yd) is parameter.
Answer:
864ft^3
Step-by-step explanation:
Divide the diameter by 2 to get the radius
12 / 2 = 6
Then solve the volume equation using 3 for pi.
4/3 * 3 * 6^3
4 * 6^3
4 * 216 = 864
Sammy calculated the total amount that he deposited by <em>adding up the total amount deposited in each account.</em>
- The Checking account is used to pay for fixed and variable essential expenses. In this account, Sammy deposited $1,712.
- The Cash account is used for non-essential expenses, like snacks, etc. A total of $260 was deposited into this account.
- The Emergency Savings account is used for both other predictable and unpredictable expenses. A total of $340 was deposited into the account.
- For the Vacation Savings account, it is used to carter for other long-term expenses. A total of $50 was deposited into the account.
- When these accounts are added up, the total deposit made by Sammy can be calculated to be $2,362 ($1,712 + $260 + $340 + $50).
Data and Calculations:
Accounts Checking Cash Account Emergency Vacations
Savings Savings
Expenses:
Essential (fixed) $1,292
Essential (variable) 420
Non-essential $260
Other predictable $130
Other (unpredictable) 210
Other (long-term) $50
Total $1,712 $260 $340 $50
Thus, Sammy calculated the total amount that he deposited by adding up the total deposit in each account.
