(a) Choose the appropriate hypotheses. Assume μ_d is the difference in average sales between the east side shop and west side shop.

a. H₀: μ_d = 0 versus H₁: μ_d ≠ 0.
b. H₀: μ_d ≠ 0 versus H₁: μ_d = 0.

(b) State the decision rule for 10 percent level of significance. (Round your answers to 3 decimal places.)

Reject the null hypothesis if t_calc <  or t_calc >  .

(c-1) Find the test statistic t_calc. (Round your answer to 2 decimal places. A negative value should be indicated by a minus sign.)
