For the past several years, the mean number of people in a household has been declining. A social scientist believes that in a certain large city, the mean number of people per household is less than 2.5. To investigate this, she takes a simple random sample of 250 households in the city, and finds that the sample mean number of people is 2.3 with a sample standard deviation of 1.3. Can you conclude that the mean number of people per...
