Answer:
By making use of a lower confidence level
Step-by-step explanation:
The margin of error is also referred to as the confidence interval and it is the system in which we use to measure the error in the result of the survey or experiment.
Now, for us to reduce the margin of error, there are different things we can do such as;
- increasing sample size
- using less data variation
- making use of a lower confidence level
- making use of a one sided confidence interval rather than a two sided confidence interval.
Looking at the above different methods of making the margin of error smaller, the one that is always under the control of the researcher is "making use of a lower confidence level".
Every other means, he does not have as much control as he has to do to lower the confidence level. That one is strictly based on his jurisdiction.
The approximate number of pink chips is 40. Here's why: what you need to do is set up the problem as shown below. 12 goes above 30 because you have to know what the total number of chips chosen is in order to relate it to 100 chips. From there, all you have to do is cross-multiply and divide (or my middle school teacher used to call it fish.... I'll explain why). First you are going to draw a line from the 100 to the 12 and multiply them. then you are going to curve the line that you will draw from the 12 to the 30 and divide the product of 12 and 100 by 30. Then you will draw a line from the 30 to the X meaning that the quotient that you find from the product of 120 and 100 divided by 30 equals X. Hope that helps.
