A random sample has been taken from a population. A statistician, using this sample, needs to decide whether to construct a 92% confidence interval for the population mean or a 98% confidence interval for the population mean. How will these intervals differ?

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer

step-by-step explanation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

r and t.

both are 64 degrees.
