Question

When sampling from same population(same sample size) as confidence level decreases confidence interval becomes wider

Answer 1

Answer:

⏩☺Increasing the sample size decreases the width of confidence intervals, because it decreases the standard error. c) The statement, "the 95% confidence interval for the population mean is (350, 400)", is equivalent to the statement, "there is a 95% probability that the population mean is between 350 and 400".☺⏪
