The Mean Annual Tuition and Fees for a Sample of 15

question 9

Multiple Choice

The mean annual tuition and fees for a sample of 15 private colleges was $35,500 with a standard deviation of $6500. A dotplot shows that it is reasonable to assume that the population is approximately normal. You wish to test whether the mean tuition and fees for private colleges is different from $32,500.
State the null and alternate hypotheses.

• A) \(H _ { 0 } : \mu = 32,500 , H _ { 1 } : \mu = 35,500\)
• B) \(H _ { 0 } : \mu \neq 32,500 , H _ { 1 } : \mu = 32,500\)
• C) \(H _ { 0 } : \mu = 32,500 , H _ { 1 } : \mu \neq 32,500\)
• D) \(H _ { 0 } : \mu = 35,500 , H _ { 1 } : \mu \neq 35,500\)
