Question 2 0/13 pts 3 2 3 0 Details For the past several years, the mean number of people in a household has been declining. A social scientist believes that in a certain city, the mean number of people per household is less than 3.5. To investigate this, she takes a random sample of 171 households in the city and finds that the mean number of people is 3.27 with a standard deviation of 1.6.
