during the month of July, an auto manufacturer gives its production employees a vacation period so it can tool up for the new model run. In surveying a simple random sample of 200 production workers, the personnel director finds that 38% of them plan to vacation out of state for at least one week during this period. Is this a point estimate or an interval estimate? Explain

In statistics, interval estimation is the use of sample data to calculate an interval of possible (or probable) values of an unknown population parameter, in contrast to point estimation, which is a single number.

This should be helpful. Thanks for asking.

This is a point estimate.

A point estimate is a single value that is used to estimate an unknown population parameter based on sample data. In this case, the personnel director surveyed a simple random sample of 200 production workers and found that 38% of them plan to vacation out of state. This 38% is a single value that estimates the proportion of all production workers who plan to vacation out of state during the specified vacation period in July.

Point estimates are commonly used when a researcher wants to estimate a population parameter, such as a mean, proportion, or difference between means or proportions, based on limited sample data. They provide an estimate of the true value but do not provide a range of possible values or any measure of uncertainty.
