[1 mark] -1 of 1 ID: MST.FET CP.DTPP.01.0020A This question relates to the patterns that occur when trying to draw inferences about one or two population means or population proportions. It is assumed in this question that any distribution. In a confidence interval estimate for a population mean or proportion, or comparing two means or two proportions, the margin of error for the confidence interval will be: O a critical value from a standard distribution Othe sample statistic that is used to estimate the relevant parameter o the product of a critical value and the standard deviation of the sampling distribution of the relevant parameter 0 the product of a critical value and the standard deviation of the population represented by the relevant parameter

Explanation / Answer

In estimating either the population mean or proportion, the general formula for the CI will be -

CI at a given level = sample statistic +- Margin of Error

Sample statistic will be the sample mean or sample proportion

Margin of error is given by either z*?/sqrt(n) or t*s/sqrt(n) for population mean based on whether the standard deviation for population is known or unknown

So, MoE = (critical value of z or t) * (standard deviation) or (critical value of z or t) * (standard error of test statistic)

So, here in our case it will be option- (D)

"the product of a critical value and the standard deviation of the population represented by the relevant parameter"
