A sample of 16 small bags of the same brand of candies was selected. The weight of each bag was then recorded. The mean weight was 2 ounces. The population standard deviation is known to be 0.1 ounce. Construct a 90% confidence interval for the population average weight of the candies. Construct a 95% confidence interval for the population average weight of the candies. Explain why the 95% interval is wider than the 90% interval. Do you think this is true always?

step-by-step explanation:

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
