mean. Type your response as TRUE or "FALSE', without the quotation marks. al) The length of a confidence interval can be determined if you know only the margin of error. b) The margin of error can be determined if you know only the length of the confidence interval. c) The confidence interval can be obtained if you know only the margin of error d) The confidence interval can be obtained if you know only the margin of error and the sample mean. e) The margin of error can be determined if you know only the confidence level. 10 The confidence level can be determined if you know only the margin of error 9) The margin of error can be determined if you know only the confidence level, population standard deviation, and sample size. h) The confidence level can be determined if you know only the margin of error, population standard deviation, and sample size.

Explanation / Answer

SolutionA:

margin of error is value to be added or subtracted form sample mean which gives length of the interval

length of intreval=sample mean-margin of error and sample mean+margin of error

FALSE

Solutionb:

FALSE

margin of error=z(for given level)*(stddev)/sqrt(sample size)

Solutionc:

FALSE

confidence interval=sample mean-margin of error and sample mean+margin of error

Solutiond

TRUE

since confidence interval=sample mean-margin of error and sample mean+margin of error
