Answer:
The correct option is (A).
Step-by-step explanation:
The (1 - α)% confidence interval for population parameter implies that there is a (1 - α) probability that the true value of the parameter is included in the interval.
Or, the (1 - α)% confidence interval for the parameter implies that there is (1 - α)% confidence or certainty that the true parameter value is contained in the interval.
The 95% confidence interval for mean number of hours worked was,
CI = (39.6 hours, 43.9 hours).
The 95% confidence interval for mean number of working hours, (39.6, 43.9) hours, implies that the true mean number of working hours for the adults of the country lies in this interval with probability 0.95.
So, there is a 95% confidence or chance that the true mean values lies in the interval (39.6, 43.9).
Thus, the correct option is (A).
