Answer:
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
20 20 because you did that in that in me I mean to see
Answer:
592.83
Step-by-step explanation:
Rectangle - 36x20=720
semi-circle=1/2x3.14x9x9=127.17
720-127.17=592.83
The rounded answer: 276,000
