Reference no: EM13947442

A Manufacturer of small electric motors believes that on average their motors draw 0.8 amps under normal load conditions. A sample of 16 motors is tested under normal load conditions and they give a mean of .663 amps and a variance of .065025. Assume that the number of amps is normally distributed. Does the sample provide sufficient evidence to conclude that the motors actually draw fewer than .8 amps under normal conditions? Test at the 1% significance level.
