A study of smartphone users shows that 68%68% of smartphone use occurs at home and a user spends an average of 410410 minutes per month using a smartphone to interact with other people (Harvard Business Review, January–February 2013). Consider the following data indicating the number of minutes in a month spent interacting with others via a smartphone for a sample of 50 smartphone users. What is the mean number of minutes spent interacting with others for this sample? How does it compare to the mean reported in the study? What is the standard deviation for this sample? Are there any outliers in this sample?
In a recent year, a sample of the South American Redeye Piranha was collected by fishermen on a particular river. Wildlife biologists regard this sample as a random sample of all Redeye Piranha in that river. The mean length of the 60 fish in the sample was 12.88 cm, and a 99% confidence level for the true mean length of all Redeye Piranha in that river is 12.09 cm to 13.67 cm. Explain what would happen to the length of the interval if the confidence level were decreased to 95%.

Explain what would happen to the length of the original interval if the sample size were decreased to 30 fish. The confidence interval will be (wider, narrower, the same) because decreasing the sample size (increases, decreases, does not affect) the margin of error.
3) Last year, the mean running time for a certain type of flash light battery was 8.5 hours. This year, the manufacturer has introduced a change in the production method which he hopes will change the mean running time. A random sample of 40 of the new light bulbs was obtained and the mean running time was found to be 8.7 hours. Do the data provide sufficient evidence to conclude that the mean running time of the new light bulbs is different from last year's mean of 8.5 hours? Perform the appropriate hypothesis test using a significance level of 0.05. Assume that standard deviation of running time of all new light bulb batteries of this type is 0.5 hours.
