Answer:
option A is correct.
Step-by-step explanation:
Minor arcs are associated with less than half of a rotation, so minor arcs are associated with angles less than 180°
Since, A minor arc is an arc smaller than a semicircle. A central angle which is subtended by a minor arc has a measure less than 180°.
The minor arc is equal to the measure of the central angle.
We could also see the angle from the figure attached to the answer.
Hence we will obtain an acute angle.
Hence, option A is correct.
Answer:
2.6549
Step-by-step explanation:
Since the sample size n=65, the degrees of freedom is n-1=65-1=64
The critical value=
Using the t-table and selecting df=64 and since it’s a 2 tail the corresponding t-score is 2.6549
Therefore, the critical value is 2.6549
