Refer to the comparison of the daily adult intake of selenium in two different regions of the united states, in exercise 8.61. suppose that you wish to estimate the difference in the mean daily intake between the two regions, correct to within 5 μg, with probability .90. if you plan to select an equal number of adults from the two regions (that is, if μ1 = μ2), how large should n1 and n2 be?

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
