Answer:
d. She should reject the null hypothesis because p < 0.10.
Step-by-step explanation:
We have a t statistic, so let's solve for the P-value on our calculators. (tcdf on a TI-84 calculator is 2nd->VARS->6.)
tcdf(left bound, right bound, degrees of freedom)
- Our left bound is t=1.457.
- Our right bound is infinity, because we're interested in the hypothesis µ>40 mg/dL. We use 999 to represent infinity in the calculator.
- Our degrees of freedom is n-1 = 15-1 = 14.
tcdf(1.457,999,14) = .084
.084 < P-value of .10, so we reject the null hypothesis.
The answer is P, because if both triangles are right angled and have the angle of 70°, then because angles in a triangle equal 180° you can say that they will be the same as 70 + 90 = 160, and 180 - 160 = 20, which is the same steps for both triangles. I hope this helps! Let me know if I need to explain it further or anything :)
