Answer:
The mean is the average of the given numbers. The median is the number in the middle of a set of given numbers and the mode is the value that appears most frequently.
The numbers must first be organized in ascending order.
120, 125, 125, 125, 130, 132, 133, 135, 135, 140, 140, 140, 140, 140, 150
In order to find the mean, all the given numbers must be added and divided by the amount of given numbers.
120+125+125+125+130+132+133+135+135+140+140+140+140+140+150=2010
2010/15=134
The mean is 134.
In order to find the median, eliminate numbers on each side until one number is remaining.
The median is 135.
In order to find mode, count each number and find the largest frequency of each.
The mode would be 140.
Assuming your retirement is more than 2 years away, and that your car purchase is not before the end of the year, the shortest-term goal of those listed is ...
... d. add $200 to your savings account by the end of the year
_____
As a teenager, "short term" may be a matter of a week or two. As a middle-aged adult, both your life-lived and life-expectancy are somwhat longer, so "short-term" can be somewhat longer as well. In old age and failing health, "short-term" may again be a matter of a few weeks at most. Such concepts are tempered by perspective.
The option that is an accurate statement about Sample Size is; A: A larger sample size is needed for increased accuracy.
<h3>What is true about Sample Size?</h3>
Sample size determination is the act of choosing the number of observations or replicates to include in a statistical sample. The sample size is an important feature of any empirical study in which the goal is to make inferences about a population from a sample.
Now, the smaller the sample size, the lesser the accuracy as you have possibility of biased research from just a handful of people. However, the larger the sample, the greater the degree of accuracy of the research.
Thus, we can say that the option that is an accurate statement about Sample Size is; A: A larger sample size is needed for increased accuracy.
Complete question is;
Which of the following is an accurate statement about sample size?
Select one:
a. A larger sample size is needed for increased accuracy.
b. A smaller sample size will reduce the size of the confidence interval.
c. Sample size is a constant percentage of the population size.
d. Sample size is independent of the confidence interval.
