A sample of 60 students has a mean weight of 45 kg. Find the Z score of a sample from a population with a mean weight of 83 kg and a standard deviation of 48 kg.
Added by Kisell C.
Step 1
Step 1:** Calculate the z-score using the formula: \[ z = \frac{{\bar{x} - \mu}}{{\sigma/\sqrt{n}}} \] where: - \( \bar{x} = 45 \) (sample mean weight) - \( \mu = 83 \) (population mean weight) - \( \sigma = 48 \) (standard deviation) - \( n = 60 \) (number of Show more…
