The process that produces Sonora Bars (a type of candy) is intended to produce bars with a mean weight of 56 gm. The process has a populationstandard deviation of0.76 gm. A random sample of 49 candy bars yields a mean weight of 55.82 gm.Which of the following statements is correctabout a test for whether the candy bars are smaller than they are supposed to be. Note that z_0.1=1.282_,z_0.05=1.645, z_0.01=2.326; with df=48, t_0.1=1.299, t_0.05=1.677, t_0.01=2.407.
