If a sample mean is 37, which of the following is most likely the range of possible values that best describes an estimate for the population mean?
O A. (28,36)
B. (32, 42)
C. (30,38)
O D. (34,42)

i believe the answer is c.

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

its line 2 i just added the rest or else it wouldn't let me answer

where is the option given
