Answer:
Step-by-step explanation:
Answer:
y = 0.36x + 4200.00
15100.00 miles.
Step-by-step explanation:
If the yearly cost for driving x miles is given by y dollars then the two ordered pairs to find the linear relation between x and y are (10000,7800) and (20000,11400).
So, the equation will be
⇒
⇒
⇒
⇒
⇒ y = 0.36x + 4200.00 ........... (1) (Answer)
Now, for y = $9636.00, from equation (1),
9636 = 0.36x + 4200
⇒ 0.36x = 5436
⇒ x = 15100.00 miles. (Answer)
<h2>
Answer with explanation:</h2>
Let p be the proportion of of all adults in the town that have been exposed to this strain of the flue .
As per given , we have
∵ is two-tailed , so the test is a two-tailed test.
Test statistic :
, where p= population proportion
= sample proportion
n= sample size
Put n= 6 and and p=0.08
P-value for two-tailed test : 2P(Z>|z|)
=2P(Z>|-0.415|)
=2P(Z>0.415)
=2[1-P(Z≤0.415)] [∵ P(Z>z)=1-P(Z≤z)]
=2(1-0.6609) [ by z-table]
=0.6782
Decision : Since the p-value(0.6782) is > significance level(0.01) , so we fail to reject the null hypothesis.
We conclude that that we do not have sufficient evidence to support the claim that the proportion of all adults in the town that have been exposed to this strain of the flue differs from the nationwide percentage of 8%.
