USING THE TRADITIONAL 5-STEP PROCESS (NO P VALUE)

--> A random sample of 450 visitors to a local shopping mall found that 90 were there to just walk the halls for exercise. Is this sufficient evidence to conclude that more than 15% of visitors to the mall were there simply for the exercise? Let α = 0.05.

--> My grandfather, Roscoe, needed a new band saw for his carpentry workshop, and asked me to call two different stores to check prices on these types of saws. Test the hypothesis that there is no difference at α = 0.02.

Store 1 :

Mean $850

s. $140

n. 15

Store 2 :

mean $730

s $120

n. 11
