Explanation:
Using the formula z=xxs where x is the data point you're evaluating, x is the mean of the data set, and s is the sample standard deviation, we plug in the numbers were given to get:
z=26030020=2

Z score for someone with 260:
It is simply how many units of "20" the persion deviates from the mean "300". The person who scores 260 deviates two standard deviations of "20" from the mean.
26030020=2

A researcher wants to see if four different strategies to combat work fatigue are independent of the gender of the person using them. She draws a sample of 200 office workers, half of them women and half men, and obtains data on which strategy the participants use to combat fatigue at work. The four strategies are: Consumption of caffeine, taking a short “power” nap, exercise, and consumption of sugar. Is the preference for a particular method of combating drowsiness independent of gender?
what statistical test should be used and why?
