I think its is 4/5 but not positive
Answer:
H0 : μ = 0.75
H1 : μ > 0.75
Step-by-step explanation:
Given :
Sample size, n = 125
x = 99
Phat = x / n = 99 / 125 = 0.792
Population proportion, P = 0.75
The hypothesis :
Null hypothesis :
H0 : μ = 0.75
Alternative hypothesis ;
Egates the null hypothesis ; since the sample proportion is greater than the the population proportion or claim "; then we use the greater than sign.
H1 : μ > 0.75
Answer:
Step-by-step explanation:
we have
we know that
In this problem
substitute in the formula
30 plus EF = 180
Ef = 150
circumscribed angle plus the central angle is 180
26 x 72 = 1872
40 + 420 + 12 = 472
1872 - 472 = 1400 (the answer)
