A freight delivery company claims that 90% of its deliveries arrive on time or are early. A sample of 100 deliveries revealed that 84 were delivered on time or were early. If Ho: p 0.90 and the p-value = 0.0228, can we conclude that less than 90% of deliveries were on time or early? Use the 5% level of significance. a) Reject Ho. Less than 90% of the deliveries were on time or early. b) Reject Ho. 90% of the deliveries were on time or early. c) Fail to reject Ho. There is insufficient evidence to suggest that less than 90% of the deliveries were on time or early. d) Fail to reject Ho. There is insufficient evidence to suggest that 90% of the deliveries were on time or early.
