multiple choice questions

14. Violating a minimum sample size requirement would can jeopardize a(n): A. confidence level B. error level C. class width D. all of the above E. only A and B 15. Consider the diagram below with two curves. Which do you suspect to be the T curve? Answer B 1 = Answer A 16. Which is true of the T curve distribution? A. When estimating a population average, the T curve has a larger variance in order to handle correction factor which must be applied to an interval estimate since little is known about o B. When estimating a population proportion, the T curve has a larger variance in order to handle correction factor which must be applied to an interval estimate since very little is known about a C. When estimating a population average, the T curve has a larger variance in order to handle correction factor which must be applied to an interval estimate since very little is known about the population proportion. D. When estimating a population average, the T curve has a smaller variance in order to handle correction factor which must be applied to an interval estimate since very little is known about the population proportion. E. When estimating a population average, the T curve has a larger median in order to handle correction factor which must be applied to an interval estimate since very little is known about the population proportion. 17. Formulas for estimating a population average when sigma is known involving using the Distribution, while formulas for estimating a population average when sigma is unknown involves and formulas for estimating population proportions involve a distribution. A. T, Z, left-skewed B.Z.T.T C. Right skewed, Z, Uniform D.T.Z, Chebychev E. None of the above are correct
