Construction of hypothesis
H₀ : p = 0.70
H₁ : p ≠ 0.70
Step-by-step explanation:
A the given statement does not give how much the goal was
lets suppose "getting rich" was an important personal goal than the proportion was 70 %
suppose that we believe that proportion has changed then construction of hypothesis for this H₀ for null hypothesis and H₁ is alternative hypothesis
Construction of hypothesis
H₀ : p = 0.70
H₁ : p ≠ 0.70
So construction of hypothesis state null and alternative hypothesis.
Answer:
Amy drove 104 miles
Step-by-step explanation:
let 'a' = miles Amy drove
let '2a' = miles Jessica drove

You are given the
length of the chain equal to 28.9cm. For each link, the length is 1.7cm long. You
are required to find how many links are there in the chain. You just divide
28.9 cm by 1.7 cm to get the answer. The solution is,
<span>
Number of links =
chain length/link length</span>
Number of links = (28.9cm)/(1.7cm)
<span>Number of links =
chain length/link length</span>
Number of links = 17
<span><u><span>There are 17
links in a 28.9cm chain length.</span></u><u /></span>
