The historical on-time percentage for Amtrak's Sunset Limited is 10 percent. In July, the train was on time 0 times in 31 runs.Hint:Use Excel to calculate the cumulative binomial probabilityP(X 0 |n= 31,= .10). Assume= .1. (a)Choose the correct null and alternative hypotheses.

1. H₀: .10 versusH₁:< .10. RejectH₀ifP< .10
2. H₀: .10 versusH₁:< .10. RejectH₀ifP> .10

multiple choice 2

• a
• b

(b)Find the probability.(Round your answer to 4 decimal places.) P(X= 0) (c-1)We can reject the null hypothesis. multiple choice 4

• Yes
• No

(c-2)Has the on-time percentage fallen? multiple choice 6

• Yes
• No
