Answer:
6.6h
Step-by-step explanation:
- So it takes 5.5 hours going at a speed of 60 miles per hour, multiply these two and we get a distance of 330 miles
- Use this distance to find the time if speed is 50 miles per hour, so time is derived by dividing the distance by the speed
- 330 miles divide by 50 miles per hour gives 6.6 hours
Answer:
The 96% confidence interval for the population proportion of customers satisfied with their new computer is (0.77, 0.83).
Step-by-step explanation:
We have to calculate a 96% confidence interval for the proportion.
We consider the sample size to be the customers that responded the survey (n=800), as we can not assume the answer for the ones that did not answer.
The sample proportion is p=0.8.
The standard error of the proportion is:
The critical z-value for a 96% confidence interval is z=2.054.
The margin of error (MOE) can be calculated as:
Then, the lower and upper bounds of the confidence interval are:
The 96% confidence interval for the population proportion is (0.77, 0.83).

If, for example, the usual price of the cycle is $4,100, and we want to know how much one could save by buying the cycle at $3,600, we must subtract $3,600 from $4,100:
$4,100
- 3,600
-----------
$500
