Answer:

And the width for the confidence interval is given by:

And we want to see the effect if we increase the confidence level for a interval. On this case if we increase the confidence level then the critical value for the confidence interval
would be higher and then the width of the interval would increase. So then the best answer for this case would be:
B. Increasing the level of confidence widens the interval.
Step-by-step explanation:
Let's assume that we have a parameter of interest
who represent for example the true mean for a population. And we can construct a confidence interval in order to estimate this parameter if we know the distribution for the statistic let's say
and for this particular example the confidence interval is given by:

Where ME represent the margin of error for the estimation and this margin of error is given by:

And the width for the confidence interval is given by:

And we want to see the effect if we increase the confidence level for a interval. On this case if we increase the confidence level then the critical value for the confidence interval
would be higher and then the width of the interval would increase. So then the best answer for this case would be:

Answer:
It can cover 203 km with 14 litres.
Step-by-step explanation:
Given that,
A car can cover a distance of 522km on 36litres of diesel.
522 km = 36 litres
1 l = (522/36) km
We need to find how far can it travel with 14 litres.
We can use the unitary method to solve it.

So, it can cover 203 km with 14 litres.
The answer is 2.75 dollars cz 11 dollars divided by 60 mins is .18 so 18 cents x 15 mins is 2.75
hope i helped u enough <span />
