Problem Set 6.3: Confidence Intervals

Criterion: Calculate confidence intervals using SPSS.

Data: Use the SPSS output from Problem Set 6.2 above.

Instruction: Based on the SPSS output from Problem Set 6.2, including a test value (population mean) of 8, calculate the 95% confidence interval.

The set of numbers/data from 6.1, and 6.2 are 8,6,12,11,8,9,14,15,10

Answer 1

Null Hypothesis: The sample has been drawn from the population with mean 8

Alternative Hypothesis: The sample has not been drawn from the population with mean 8

P-value is less than 0.05. So, we can conclude that the sample has not been drawn from the population with mean 8.
