You want to introduce this new pie only if the population mean of da sales is greater than $350 per day. Using hypothesis testing to see if you should add the new pie, with an alpha leve 0.05, what is the value of the standard error of your sample mean, accurate to tv decimal places? 34.75 1.73 0.44 23.54 17.93
