Here is a scenario:
Mark recorded the following bowling scores for his last 9 games:
110, 92, 86, 203, 74, 105, 97, 112, 99
What was his mean score?
What was his median score?
Which of these better represents his bowling score for the last nine games?
Answer:
1 3/5
Step-by-step explanation:
The distance between 1 and 2 is 5 units. Therefore, Point D is 3/5 of the way to 2.
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:
B. Increasing the level of confidence widens the interval.
Answer:
i think 648
Step-by-step explanation:
Area = Length times width
18 times 36 = 648
But It could be 3,240
18 times 36 times 5
