Answer:
-2.23 ; 0.012874
Step-by-step explanation:
Given that :
Population mean (μ) = 25 minutes
Same mean (x) = 24min 12 seconds = 24.2 minutes
Standard deviation σ = 3
Sample size (n) = 70
Test statistic :
Using the relation :
Tstatistic = (x - m) / σ/sqrt(n)
Tstatistic = (24.2 - 25) / (3/sqrt(70)
Tstatistic = - 0.8 / 0.3585685
Tstatistic = - 2.2310939
= - 2.23
The P value can be obtained using a. P value Calculator :
P at α = 95% and test statistic = - 2.23
Hence, p = 0.012874 using calculator
Answer:
Yes
Step-by-step explanation:
Pythagorean theorem states that for right triangles a^2 + b^2 = c^2, which is true for this as a^2 = 1225 + 144 (b^2) = 1369,
1369 = 37^2
