The concentration of active ingredient in a liquid laundry detergent is thought to be affected by the type of catalyst used in the process. the standard deviation of active concentration is known to be 3 grams per liter, regardless of the catalyst type. ten observations on concentration are taken with each catalyst, and the data follow: catalyst 1: 57.8, 66.4, 65.4, 65.4, 65.2, 62.6, 67.6, 63.7, 67.2, 71.0 catalyst 2: 67.6, 71.1, 70.3, 69.3, 64.8, 69.6, 68.6, 69.4, 65.3, 68.8 (a) find a 95% two-sided confidence interval on the difference in mean active concentrations for the two catalysts. find the p-value

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
