Please answer both questions in explanation!

An Internet service provider states that the average number of hours its customers are online each day is 3.12. Suppose a random sample of 14 of the company's customers is selected and the average number of hours that they are online each
day is measured. The sample results are shown in the accompanying table.
3.54
3.79
6.11
6.13
3.66
2.23
7.93 D
5.93
7.61
3.67
6.29
3.17
5.49
1.14
Based on the sample of 14 customers, how much sampling error exists? Would you expect the sampling error to increase or decrease if the sample size was increased to 40?
Based on the sample of 14 customers, how much sampling error exists?
The sampling error for the given sample is ||.
(Round to four decimal places as needed.)
