The data below represent a random sample of the number of home fires started by candles for the past several years. (From the National Fire Protection Association.) Find the 90% confidence interval for the mean number of home fires started by candles each year. 5560 5900 6090 6210 7160 8440 9930 Which of the following is the Real World Interpretation? There is a 90% chance that 5864.5 < µ < 8218.4 contains the true mean number of home fires started by candles each year. 90% of the home fires started by candle each year is between 6045.2 and 8037.7. The mean number of home fires started by candles each year is between 6045.2 and 8530.7 fires. 90% of the home fires started by candles each year is between 5864.5 and 8218.4. There is a 90% chance that 5864.5 < µ < 8218.4 contains the true mean. There is a 90% chance that 6045.2 < µ < 8037.7 contains the true mean number of home fires started by candles each year. The mean number of home fires started by candles each year is between 5864.5 and 8218.4 fires.
