What are the exact values of sin(2π/3radians) and cos(2π/3radians)?

1 answer:

6 0

Sin(2π/3radians) = sin(π/3radians) = (√3)/2cos(2π/3radians) = - cos(π/3radians) = 1/2

becuase 2π/3 + π/3 = π

The formula for the confidence interval is given by

Sample mean + z*[σ/√n], and
Sample mean - z*[σ/√n]

We have:
Sample mean = 23.95
n = 40
σ = 2.55
z* for 99% confidence = 2.58

Substitute these values into the formula, we have

23.95 + (2.58)(2.55÷√40) = 24.99
23.95 - (2.58)(2.55÷√40) = 22.91

So the lower interval is 22.91 and the highest interval is 24.99
