340 and 0.034 because yo move two decimal points to the left
Answer:
Use the normal distribution if the population standard deviation is known.
Use the student's t distribution when the population standard deviation is unknown.
Explanation:
A mound-shaped distribution refers to the normal distribution.
A good sample size for testing against the normal distribution should be
n >= 30.
The condition for the sample size is satisfied.
However, we are not given the population standard deviation, therefore it is assumed to be unknown.
Therefore the student's t distribution should be used.
Answer:
it's D
Step-by-step explanation:
it's d because if 74 would be the same as the left side next to x and if you turn that into a problem like 180-74 and I got 180 cause half of a circle is 180 and then my answer would be 106 I'm not good at explaining but it's d
Only D is correct, it intersects at 90 degrees so it cant be obtuse or acute and never intersecting would be parallel lines <span />
