Answer:
number of miles = 9.25 miles = 9 and 1/4 miles

Explanation:
For simplicity, I will convert the mixed numbers into decimals to ease the calculations. Then I will convert the final answer back into a mixed number.
So,
3 and 7/10 miles = 3.7 miles
2 and 1/2 hours = 2.5 hours

Now, we are given that the rate of the car is 3.7 miles per hour. To know the time taken by the car to travel 2.5 miles, we will simply do cross multiplication as follows:
3.7 miles ................> 1 hour
?? miles ................> 2.5 hous
number of miles = (2.5*3.7) / 1 = 9.25 miles

Now, converting this back into mixed number, we will find that:
number of miles = 9.25 miles = 9 and 1/4 miles

Hope this helps :)

A political pollster conducted a study to determine political party loyalty. To do so, he selected a random sample of 100 regist
Reika [66]

Answer: (a)

P - Value = 0.0981 is high, this indicates stronger evidence that we should fail to reject the null hypothesis: H0: pD = pR (There is no significant difference between the proportion of Democrats who plan to vote for the Democratic candidate in the upcoming election and the proportion of Republicans who plan to vote for the Republican candidate in the upcoming election). P - Value = 0.0981 is the probability of obtaining results at least as extreme as the observed results of the Hypothesis Test, assuming that the null hypothesis is correct.

(b)

Since P - Value = 0.0981 is greater than \alpha = 0.05, the difference is not significant. Fail to reject null hypothesis.

(c)

Since in the Hypothesis Test, we have failed to reject null hypothesis, we could have made: Type II Error: Failure to reject a false null hypothesis. One potential consequence of this error is as follows:

Suppose in reality there is significant difference between the proportion of Democrats who plan to vote for the Democratic candidate in the upcoming election and the proportion of Republicans who plan to vote for the Republican candidate in the upcoming election. But the political pollster wrongly concludes that there is no significant difference between the proportion of Democrats who plan to vote for the Democratic candidate in the upcoming election and the proportion of Republicans who plan to vote for the Republican candidate in the upcoming election. Type II Error is committed in this situation. The consequence of this Type II Error is that the political pollstar will that the political parties are loyal and will not do any follow up work whereas in reality it is not so.
