A family restaurant claims that the average family of 4 can enjoy a meal far $100 or less. One night, 65 families of 4 ate at the restaurant and the average amount spent was $96 with a standard deviation of $21. With a=0.05, do yau have endugh evidence to reject the restaurant's claim?

(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
