Whenever the population standard deviation is unknown and the population has a normal or near-normal distribution which distribution is used in developing an interval estimation? whenever the population standard deviation is UNKNOWN and the population has a normal or near-normal distribution which distribution is used in developing an interval estimation ? becomes smaller As the number of degrees of freedom for a t distribution increases the difference between the t distribution and the standard normal distribution 10. In interval estimation the t distribution is applicable only when a. the population has a mean of less than 30 b . the sample standard deviation is used to estimate the population standard deviation c. the variance of the population is known d. the standard deviation of the population is known Whenever the population standard deviation is unknown and the population has a normal or near-normal distribution which distribution is used in developing an interval estimation ? a. standard distribution b. z distribution c. alpha distribution d. t distribution Whenever the population standard...
