Working at Home Workers with a formal arrangement with their employer to be paid for time worked at home, worked an average of
hours per week. A random sample of
mortgage brokers indicated that they worked a mean of

, is there sufficient evidence to conclude a difference? Construct a
confidence interval for the true mean number of paid working hours at home. Compare the results of your confidence interval to the conclusion of your hypothesis test and discuss the implications.
(a) State the hypothesis and identify the claim with the correct hypothesis.

decimal places, if necessary.
What's the null hypothesis?
| There ▼(Choose one) enough evidence to support the claim that there is ▼(Choose one) from the stated average of 19 hours per week. |

<u<
Compare the results of your confidence interval to the conclusion of your hypothesis test and discuss the implications.
|
Because the mean ▼(Choose one) in the interval, there is ▼(Choose one) to support the claim that ▼(Choose one) exists.
