The activation temperature (in â¦F) of a sprinkler system, Y , is normally distributed with population mean µ and population variance Ï 2 = 52 . A random sample of n = 10 sprinklers is obtained and the activation temperature is recorded for each sprinkler. The sample mean is Y = 120. Required:
a. Calculate a 95% confidence interval for µ.
b. What is the standard error of the sample mean?
c. What is the margin of error of the confidence interval in (a)?

Part a what is the area of triangle i? show your calculation. part b triangles i and ii are congruent (of the same size and shape). what is the total area of triangles i and ii? show your calculation. part c what is the area of rectangle i? show your calculation. part d what is the area of rectangle ii? show your calculation. part e rectangles i and iii have the same size and shape. what is the total area of rectangles i and iii? show your calculation. part f what is the total area of all the rectangles? show your calculation. part g what areas do you need to know to find the surface area of the prism? part h what is the surface area of the prism? show your calculation. part i read this statement: “if you multiply the area of one rectangle in the figure by 3, you’ll get the total area of the rectangles.” is this statement true or false? why? part j read this statement: “if you multiply the area of one triangle in the figure by 2, you’ll get the total area of the triangles.” is this statement true or false? why?
