Acoin mint has a specification that a particular coin has a mean weight of 2.5 g. a sample of 34 coins was collected. those coins have a mean weight of 2.49607 g and a standard deviation of 0.01633 g. use a 0.05 significance level to test the claim that this sample is from a population with a mean weight equal to 2.5 g. do the coins appear to conform to the specifications of the coin mint?

if you explain the the question more correctly i might be able to answer this better

step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

can you put the picture up?
