2 times 4.95 equals 9.9
16.56 times 6 equals 99.36
add it up and it’s 109.26
Answer:
The requirements for a z-confidence interval are met because the sample is a simple random sample from a normal distribution with a known population standard deviation.
Step-by-step explanation:
The requirements for a z-confidence interval are met because the sample is a simple random sample from a normal distribution with a known population standard deviation.
However, since the sample is small, we should use the Student's t-distribution with 5 degrees of freedom (sample size-1) instead of the Normal distribution.
The t-distribution is the right choice when the data distribution is approximately normal and the sample size is less than 30.
The t-confidence interval will depend on the level of confidence desired.
Answer:
90 degree
Step-by-step explanation:
Let represent the measure of the third angle. Then, − can represent the measure of the second angle. The
sum of the two angles in the right triangle will be °.
− + =
− =
− + = +
=
=
=
The third angle is and therefore measures °. Replacing with in − gives () − = − = .
Therefore, the measure of the second angle is °. The measure of the third angle is °.
