Hypothesis Test Information: A local computer company wants to test a claim that new computer buyers spend an average of $3,000 ( μ ) on their initial hardware and software purchase with a standard deviation of $400 ( σ ) . The company manager sampled 25 (= n) new computer buyers and found their average expenditure to be $2,750 (= x-bar). Use this information to answer the next several hypothesis testing questions.
Problem a - Hypothesis Test Sampling Distribution: Based on the above information, what is the appropriate sampling distribution to use in this hypothesis test?
Binomial Distribution
Poisson Distribution
z - Distribution
t - Distribution
