Check out the drawing below. The triangles are to scale.
- Angle A of triangle ABC is between sides AB = 3 and CA = 6
- Angle P of triangle PQR is between sides PQ = 3 and RP = 6
So far, we have two sides that are 3 units long (AB and PQ) and two sides that are 6 units long (CA and RP) when we compare the angles A and P.
The difference is that side BC = 4 is shorter than QR = 5. This is the exact reason why angle A is smaller than angle P. The smaller the opposite side gets, the smaller the angle gets, and vice versa. Think of it like a door. As the door opens further, the distance from the door handle to the door frame increases which in turn increases the angle.
Answer: the t-test statistic is - 1.77
Step-by-step explanation:
For the null hypothesis,
H 0: μ = 2600
For the alternative hypothesis,
H a: μ ≠ 2600
This is a two tailed test
Since no population standard deviation is given, the distribution is a student's t.
Since n = 50,
Degrees of freedom, df = n - 1 = 50 - 1 = 49
t = (x - µ)/(s/√n)
Where
x = sample mean = $2450
µ = population mean = $2600
s = samples standard deviation = $600
Therefore,
t = (2450 - 2600)/(600/√50) = - 1.77
