Question: Get a simple random sample of 40 people in Santa Cruz County. Ask them how much time they spent on their phone yesterday (in hours). Note: You can make up these 40 values,
- What are the 40 sample data values?
- What is the mean of your simple random sample? Round to 1 decimal place.
- What is the standard deviation of your simple random sample? Round to 2 decimal places.
-
Use this information to construct a 95% confidence interval for the mean time of all people in Santa Cruz County spend on their phone in a day. Use the 4 step method as shown in the Chp. 8 lecture videos. As a reminder the 4 step process is:
- Find the critical value. Round to 2 decimal places.
- Find the margin of error. Round to 2 decimal places.
- Construct the confidence interval using inequality notation (ie. "<")
- Write an interpretation of your interval using proper units.
