Question

Suppose a survey of 36 people determined that the sample mean time spent on the internet was 8.2 hours with a sample standard deviation of 9.8 hours.

What is the critical value for a 95% confidence interval?

Note: Enter X.XX AT LEAST ONE DIGIT BEFORE THE DECIMAL, TWO AFTER and round up. Thus, 7 is entered as 7.00, 3.5 is entered as 3.50, 0.3750 is entered as 0.38

What is the Margin of Error for a 95% confidence interval?

Note: Enter X.XX AT LEAST ONE DIGIT BEFORE THE DECIMAL, TWO AFTER and round up. Thus, 7 is entered as 7.00, 3.5 is entered as 3.50, 0.3750 is entered as 0.38

What is the UPPER BOUND of the 95% confidence interval?

Note: Enter X.XX AT LEAST ONE DIGIT BEFORE THE DECIMAL, TWO AFTER and round up. Thus, 7 is entered as 7.00, 3.5 is entered as 3.50, 0.3750 is entered as 0.38

What is the LOWER BOUND of the 95% confidence interval?

Note: Enter X.XX AT LEAST ONE DIGIT BEFORE THE DECIMAL, TWO AFTER and round up. Thus, 7 is entered as 7.00, 3.5 is entered as 3.50, 0.3750 is entered as 0.38

Suppose a survey of 36 people determined that the sample mean time spent on the internet was 8.2 hours with a sample standard deviation of 9.8 hours.

What is the critical value for a 99% confidence interval?

Note: Enter X.XX AT LEAST ONE DIGIT BEFORE THE DECIMAL, TWO AFTER and round up. Thus, 7 is entered as 7.00, 3.5 is entered as 3.50, 0.3750 is entered as 0.38
