Question
help solve 30-35 please
Normal Distribution and z- Score y ormal distribution curve: h, the and the median will always be equal e mean median, and mode will always be equal 31. In normal probability distribution curve, the tails ofthe curve: values of the distribution end al +/-3 sigma b. end at 6 sigma values of the distribution flatten out and extend indefinitely along the horizontal axis without 1ouching 32 The standard deviation: distribution a gives the of the consistency of the process dana gives an approximation of the size of central tendency a degree freedom in the formula fora population important measure of central tendency 13. Approximately 95% of all measurements in a normal curve: a. are ncluded in the to-1 standard deviation b are included in the mean 2 standard deviation are included in the mean 3 standard deviation 34. Which technique is best for determining the area under the normal curve? a. Central Tendency b. Coefficient of Variance later Schwbart's formula d. Z-statistics 35. The central theorem when sufficient number of samples of size n 5 to 12 are taken for Limit predicts the population statistical analysis, the standard deviation Sx of sample means a si is greater than o none of the above
Explanation / Answer
30. Correct Answer: Option (C)
Since
