Answer:
PLEASE HELP!!!
1. Under what conditions must we assume a Student t distribution for the sampling distribution of sample means when testing a claim about a population mean?
2. Give one difference between the Student t distribution and the normal distribution.
3. Which TI-84 calculator command or StatCrunch dialog box is used to find the P-value given a t test statistic?

The answer is 2/6 because both of the numbers can be divided by 2. 4/2 is 2 and 12/2 is 6
Answer:
z = 1
Step-by-step explanation:
Since this is an equation we can cross multiply the fractions
7/z = 84/12 ➡ 84×z = 7×12
84z = 84 divide both sides by 1
z = 1
Answer:
x = 27
Step-by-step explanation:
Since AC and DE are parallel lines, then
∠ BAD = ∠ EDF= 2x ( corresponding angles )
The sum of the 3 angles in Δ BAD = 180°, thus
2x + 2x + 72 = 180, that is
4x + 72 = 180 ( subtract 72 from both sides )
4x = 108 ( divide both sides by 4 )
x = 27
