The lowest and highest observations in a population are 14 and 48, respectively. What is the minimum sample size n required to estimate μ with 90% confidence if the desired margin of error is E = 1.5? What happens to n if you decide to estimate μ with 95% confidence? (You may find it useful to reference the z table. Round intermediate calculations to at least 4 decimal places and "z" value to 3 decimal places. Round up your answers to the nearest whole number.)
