Answer:
<u>The standard error of the mean is 0.444</u>
Step-by-step explanation:
1. Let's review the information given to us for solving the question:
Size of the sample = 25
Mean amount of money spent per day = US$ 18.01
Standard deviation = US$ 2.22
2. For finding the standard error of the mean, we use the following formula:
Standard error = Standard deviation / √Size of the sample
Standard error = 2.22 / √25
Standard error = 2.22 / 5
<u>Standard error = 0.444</u>
3. Interpretation of the standard error:
The standard error is "the standard deviation of the population of values of a sample statistic in a repeated sampling or its estimate".
Thus, the potential for error in the reported result is not more than ± 0.444 (68% confidence) or no more than 1.96 times the standard error (0.444) = ± 0.87 (at 95% confidence).
