We use the t distribution to construct aconfidence interval for the population mean when the underlyingpopulation standard deviation is not known. Under the assumptionthat the population is normally distributed,find tα/2,df forthe following scenario:
A 95% confidence level and a sample of 28 observations. Enterthe answer rounded to three decimal places.
