Cyberdyne Systems is currently working on changes to the mobility of it's T800 Model cyborgs. They have used an experimental alloy in 34 new cyborg units and have found that they can travel at an average sustained speed of 37.43 kilometres per hour, with a standard deviation of 5.69, without suffering structural damage. T800s are generally capable of sustained speeds of 35.41 kph on average, with a standard deviation of 8.12.

Calculate a two-tailed z-test with an alpha level of .05, to determine whether the new model is significantly different from the speed of the general population of cyborgs. Also compute and interpret the effect size and the 95% confidence interval.

STEP 1: Identify the populations, distribution and assumptions, and the choose the appropriate test.

Population 1 =

Population 2 =

STEP 2: State the Null and Research Hypotheses in symbols and words.
