A store owner claims the average age of her customers is 35 years. She took a survey of 30 randomly selected customers and found the average age to be 36.1 years with a standard error of 0.506 Carry out a hypothesis test to determine if her claim is valid
Which hypotheses should be tested?
a. H₀ : μ = 361 versus Hₐ : μ ≠ 361
b. H₀ : p = 35 versus Hₐ : p ≠ 35
c. H₀ : μ = 35 versus Hₐ : μ ≠ 35
d. H₀ : μ = 35 versus Hₐ : μ > 35
