False
Step-by-step explanation:
Steps in calculating confidence Interval are
- Calculate degree of freedom by subtracting 1 from sample size that is df=sample size -1
- find α by subtracting confidence interval level from 1 and divide by 2
- Use value ot α and df to determine t from t-distribution table. From table it can be seen that the value of t increases as value of df decreases
- Divide standard distribution by square root of sample size. As sample size decreases this value will increase
- Multiple step 3 by step 4. We can say, if sample size is decreased this value will increase.
- For lower end , subtract step 5 from sample mean and for upper end add step 5 to sample mean.
If sample size is decrased, step 3 and step 4 will increase. As a result result obtained from step 5 will also increase. Hence, confidence interval will increase if sample size is decreased
17.29 feet, using the Pythagorean theorem.
Answer:
-1
Step-by-step explanation:
If 5 + 7 = 17
5 + 7 + ? = 17
5 + 7 = 12 so 17-12 + 5
5 = N
N - 6 = ?
5 - 6 = -1
If Naya is filling up the gas tank in her motorcycle she puts 4.145 gallons of gas in the tank if the gas cost $2.57 per gallon then she spend $10.65
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given,
The cost of one gallon of gas =$2.57
The quantity of gas she puts in the tank = 4.145 gallons
Apply unitary method
Then, the cost of 4.145 gallons of gas = Cost of one gallon of the gas × Quantity of gas
The cost of 4.145 gallons of gas= 2.57×4.145= $10.65
Hence, If Naya is filling up the gas tank in her motorcycle she puts 4.145 gallons of gas in the tank if the gas cost $2.57 per gallon then she spend $10.65
