Answer:
The null hypothesis can't be rejected.
Step-by-step explanation:
Given information:
Null hypothesis:
H₀ : π ≤ 0.70
Alternative hypothesis:
H₁ : π > 0.70
We need to check whether the null hypothesis is rejected or accepted.
If P-value < α, then we reject the null hypothesis H₀.
If P-value ≥ α, then we accept the null hypothesis H₀.
A sample of 100 observations revealed that p = 0.75 at the 0.05 significance level.
Here 0.75>0.05, it means p > α, therefore we can not reject the null hypothesis.
Answer:
x = - 6
Step-by-step explanation:
Given
= 3
Multiply both sides by 5 to clear the fraction
9 - x = 15 ( subtract 9 from both sides )
- x = 6 ( multiply both sides by - 1 )
x = - 6
