population?Student Answer:The level of confidence in estimating the population parameter The size of the population The maximum allowable error in estimating the population parameter An estimate of the population variation Question 18.Question :How is the tdistribution similar to the standard zdistribution?Student Answer:Both are discrete distributions. Both are skewed distributions. Both are families of distributions. Both are continuous distributions.
Question 19.Question :A bank wishes to estimate the mean credit card balance owed by its customers. The population standard deviation is estimated to be $300. If a 98% confidence interval is used and an interval of $75 is desired, how many customers should be sampled?
