Comparing Means
Restaurateur Danny Valentine is
evaluating two, sites, Raymondville and Rosenber, for his next restaurant.
Denny suspects that Raymondville residents (population 1) dine out more often
(number of times per month) than Rosenberg residents (population 2).
Denny commissions a market survey
to test his hypothesis. The market researcher used a random sample of 64
families from each suburb and recorded the number of times each population
dines out.
The market researcher finds that
the sample difference in the mean number of dine out times is 3.54 population1
– population 2. The calculated two-tail p-value =.03. Assuming alpha=.02
Should the hypothesis null
hypothesis be rejected or accepted, or the alternate hypothesis?
