True or False:

1. For a specific confidence interval, the larger the sample size, the smaller the margin of error will be.

2. The best point estimator of the population mean is the sample mode.

3. When the population standard deviation is unknown, a value should be used in computing a confidence interval for a mean is Z.

4. When a 99% confidence interval is calculated instead of a 95% confidence interval with n being the same, the margin of error will be larger.

(Answer all please. I'll give rate. Thanks)

Definition Definition Measure of central tendency that is the value that occurs most frequently in a data set. A data set may have more than one mode if multiple categories repeat an equal number of times. For example, in a data set with five item—3, 5, 5, 29, 473—the mode is 5 because it occurs twice and no other value occurs more than once. On a histogram or bar chart, the element with the highest bar represents the mode. Therefore, the mode is sometimes considered the most popular option. The mode is useful for nominal or categorical data (e.g., the most common color car that users purchase), but it is problematic for continuous data because it is more likely not to have any value that is more frequent than the other.
