Transcribed Image Text:c. What is the conclusion?
Reject Ho since the p-value is greater than the significance level.
Reject Ho since the p-value is less than the significance level.
Do not reject Ho since the p-value is greater than the significance level.
Do not reject Ho since the p-value is less than the significance level.
We conclude that the population mean is less than 155.
