Question 1
A _______________ for a population parameter is an interval of values constructed so that, given a specified degree of confidence, the value of the population parameter lies within this interval.
◦
confidence level
◦
confidence coefficient
◦
convergence interval
◦
confidence interval
Question 2
A 95% confidence interval estimate of the population meanμcan be interpreted to mean that:
◦
if we repeatedly draw samples of the same size from the same population, 95% of the values of the sample means\(\style{font-family:Times New Roman;}{\overline x}\) will result in a confidence interval that includes the population meanμ.
◦
there is a 95% probability that the population meanμ will lie between the lower interval limit and the upper interval limit.
◦
we are 95% confident that we have selected a sample whose range of values does not contain the population meanμ.
◦
we are 95% confident that 5% of thevalues of the sample means\(\style{font-family:Times New Roman;}{\overline x}\) will result in a confidence interval that includes the population meanμ.
