An article in the ASCE Journal of Energy Engineering (1999. vol. 125, pp. 59-75) describes a study of the thermal inertia properties of autoclaved aerated concrete used as a building material. Five samples of the material were tested in a structure, and the average interior temperatures (degree C) reported were as follows: 23.01, 22.22, 22.04, 22.62, and 22.59. a) Test the hypotheses H0: mu. = 22.5 versus H1: mu, 22.5, using a = 0.05. Find the P-value.
b) Check the assumption that interior temperature is normally distributed.
c) Compute the power of the test if the true mean interior temperature is as high as 22.75.
d) What sample size would be required to detect a true mean interior temperature as high as 22.75 if we wanted the power of the test to be at least 0.9?
e) Explain how the question in part (a) could be answered by constructing a two-sided confidence interval on the mean interior temperature.

e) none of the above because the measure of angle cba is 101°

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc

i think you would have to divide the money he had saved, which is $2,000 by the time he plans on exercising which is 40 hours, and the answer you get should tell you the answer to your question.
