A research report says that t(63) = 1.99; p = .03. From that information, can you reject the null hypothesis with 95% confidence
Leona [35]

Answer:

Yes, I can reject the null hypothesis with 95% confidence.

Step-by-step explanation:

Critical value t(63) = 1.99

p-value = 0.03

Confidence level (C) = 95% = 0.95

Significance level = 1 - C = 1 - 0.95 = 0.05

Conclusion:

Reject the null hypothesis because the p-value 0.03 is less than the significance level 0.05.

Find segment ET. Please and thank you​
Solnce55 [7]

Answer:

x=9

Step-by-step explanation:

Use the intersecting chord theorem:

RE*ET = UE*ES

Substitute values

21 (2x+2) = 30 (x+5)

Expand:

42x+42 = 30x + 150

transpose and simplify

42x-30x = 150 - 42

12x = 108

x = 9

If the measure of arc GH= 90° and the measure of arc EF= 45°, calculate m∠GDH.
user100 [1]

Answer:

∠ GDH = 67.5°

Step-by-step explanation:

The measure of the chord- chord angle GDH is half the sum of the measures of the arcs intercepted by the angle and its vertical angle.

∠ GDH = \frac{1}{2}(GH + EF) = \frac{1}{2} (90 + 45)° = 0.5 × 135° = 67.5°
