Answer: d) 2.045</h3>
Use either a table or a calculator to find this value. The t table should be found in the back of your stats textbook (if you dont have a textbook then you can find a free online t table by searching it out). See the attached image below for how I used a table to get the answer.
If you use a calculator, then you'll use the inverse T function. If n > 30, then you would be able to use a Z distribution instead of a T distribution which would mean that z = 1.96 is the critical value used. But instead, n = 30 does not make n > 30 true. Keep in mind that the degrees of freedom (df) are df = n-1 = 30-1 = 29.
Answer:
C
Step-by-step explanation:
Since the angles at the centre subtended by the congruent arcs WX and YZ
Then ∠YOZ = ∠WOX = 103° → C
