C. use minitab express to construct a standard normal distribution to identify the z* multiplier for a 99% confidence interval (i. e., identify the z values that separate the middle 99% from the outer 1%). copy+paste your distribution here. clearly identify your final answer. d. use the observed sample mean, observed standard error, and the z* multiplier that you found in part c to construct a 99% confidence interval to estimate the population mean. use the general form of a confidence interval: sample statistic ± z*(standard error) e. interpret your confidence interval.

An electronics manufacturer wants to know if customers would be interested in a detachable keyboard for their tables and if so, what the most important features would be. the manufacturer partners with an electronics store to include copies of the survey with every purchase at that store for one week. which of the following best explains why this random sample is unlikely to be a good representative sample of tablet owners' preferences for a detachable keyboard? a) one week is likely not enough time to get a large enough sample. b) most people won't bother to send in the survey, which is likely to skew the results c) there is no way to verify whether the responders to the survey actually own a tablet d) the survey is biased because it was conducted through an electronics store, not the general population
