Imagine that you are next interested in discovering whether or
not there are differences in minutes spent exercising per day
between males (coded as “1”) and females (coded as “2”) in your
sample. You hypothesize that males exercise more minutes per day
than females. You performed descriptive analyses and found that
minutes spent exercising was approximately normally distributed in
both groups (skewness = .26 for males, skewness = .07 for females).
You therefore decided to perform an independent samples t...

Q2. Hypothesis Testing with a Z test (14 points total) A research institute examined the number of smart phones and tablets connected to the internet in American households and reported a mean (μ) of 5 devices per household and a standard deviation (σ) of 1.5 devices. But I wonder if the statistics in my neighborhood, Chandler, would be different from the national average. To test this idea, I randomly picked 16 friends of mine living in Chandler and asked them...
