Data from a 2006 GSS subsample show that the mean number of children per respondent was 1.87, with a standard deviation of 1.64. A total of 1,494 people answered this question. Estimate the population mean number of children per adult using a 90% confidence interval. We our 90% confident that the population mean number of children per adult is between to . Please round to the nearest tenth For example, rounding 0.843 to the nearest tenth would give 0.8.

We are 90% confident that the population mean number of children per adult is between 1.8 to 1.9.

Step-by-step explanation:

The confidence interval for population mean is given by:-

, where n= sample size, = sample mean, z* = critical value for confidence level, = standard deviation.

z*  for 90% confidence level = 1.645

As per given, the required confidence interval is

Hence, We are 90% confident that the population mean number of children per adult is between 1.8 to 1.9.
