The mean age when people got married for the first time in the year 2000 was 26 years old with a population standard deviation of 6 years. A researcher thinks that marriage age has significantly changed since then. A survey of married persons of this generation was done to see if the mean age has changed. The sample of 50 married persons found that their mean age of first marriage was 27.7 years old. Do the data support the claim at the 10% significance level? What are the correct hypotheses?

Australian Bureau of Statistics (ABS) reports that the average cost of household energy consumption is continuously increasing from the last ten years. A team of research students surveyed 120 middle-class families in order to understand current utility expenses. They also found that the average cost of those 120 households’ energy consumption is $1800 per year and the population standard deviation is $200. What is the margin of error at a 95% confidence level?

The mean age when smokers first start is 13 years old with a population standard deviation of 1.9 years. A researcher thinks that smoking age has significantly changed since the invention of ENDS-electronic nicotine delivery systems.
